Link to diagrams of the branching of G clusters and discussion about these clades.

Note: this page has adopted a tentative new classification of haplogroup G subgroups.  Link to
the page showing
branching of G clusters  for a full explanation. 

The deduced information here is primarily from the YHRD database  — except as noted.  Caution must be observed in interpreting this information because it is not known what criteria the contributors used in selecting test subjects for YHRD.  It is unlikely that any sample set meets criteria for a truly random selection of persons in that area.

Use the link above for information on the branching of G clusters and marker anomalies that characterize various clusters.  Reference will be made in the descriptions below to a U8* cluster.  This refers to the most typical G values in a geographical belt from Ireland to Switzerland where marker values are dominated by DYS388= 13.  These U8* persons comprise the most common samples available in the commercial labs, and the likely percentage of this U8* type in each country will thus be mentioned below.  Knowing this U8* percentage may be helpful in determining the origins of these DYS388= 13,  U8* persons.  The U8* is a temporary designation representing a new SNP mutation found by Garvey et al. in late 2006.  It will perhaps be used to designate as a new G2a subcategory, G2a3*, but this is not certain depending on whose discoveries are officially added to the categories first.  When reference is made below to the U8* cluster, these are specifically the DYS388= 13 persons.

The Caucasus Mountains (11 to 74 percent G)
The locations in the Caucasus Mountains as represented in the YHRD database have the following G information.  [These are basically the same persons in the Nasidze article so their haplogroups have been determined by SNP testing]

Northwest of the Caucasus:
>Kabardinian people , S. W. Russia, northwestern Caucasus.  Known to be 29 % G.   About half of the 17 men have unusual DYS 385 values of 13,14.  This profile also dominates in the western portion of the old Soviet Union.   Several persons also are likely in the U8* cluster.
>Ingushian people  -- near to the Kabardinians in northwestern Caucasus.  Known to be 27 % G in a small sample. Because of overlap into other haplogroups, not all the G people are obvious.  None of the ones that are recognizable match U8* cluster persons.
>Digora, N. Ossetia-Alania, central Caucasus, S. W. Russia.  Known to be 74% G.   17 of 24 of the tested men have an unusual 11/28 value for DYS 389.  This is quite different from anything found in western Europe, but there are a few cases of this combination in eastern Europe.  It is suspected, but not proven, that these men are G2a1.   Among the remaining 7 Digora samples, three men are probably U8* cluster persons.  The N. Ossetians claim to be remnants of the Alans, but they are genetically different from the groups in western Europe who were also called Alans. 
>Ardon, N. Ossetia-Alania  -- central Caucasus, S. W. Russia.  Of the 28 tested men, it is known 21% are G.  None are close matches to U8* cluster persons.  There are two in the Ardon group who have the 11, 28 (at DYS 389) that predominates in Digora, but the sample size is small, making valid conclusions difficult.
>Alagir, Zamankul, Ziga, N. Ossetia-Alania, central Caucasus, S. W. Russia.  In a second study by Nasidze, he found 51 additional G samples among 70 total samples. These represented 75%, 61% and 60% respectively of the total men sampled there. These haplotypes are displayed at the Whit Athey G website, but the 51 are several more than would be expected.  Did the author add a few?  The 11,28 (at DYS 389)  is again extremely common at these locations and probably respresents G2a1a persons.

Northeast of the Caucasus:
> Rutulia, S. W. Russia    Known to be 38% G.  However the DNA values obtained here have no counterpart at all to those west of the Caucasus and are considerably genetically distant from those found in the U8* cluster.
> Lezginians, S. W. Russia   Known to be 32% G in a small sample of 19 men.  The DNA pattern has little in common with those of U8* cluster persons, but, unlike Rutulia, is a little closer to the DNA patterns to the west . Like the Kabardinians, about half have the unusual DYS 385 values of 13,14 or something similar.
>Darginians, S. W. Russia.  In a small sample of 26 men, found to be 4% G.  The DNA profile of the sole individual G person is not obvious.
>Chechnia, S. W. Russia   [It is actually close to the midpoint of the north Caucasus.]  In a small sample of 19 men, 5% found to be G.  The DNA profile of the sole individual G person is not obvious.

South of the Caucasus: 
>Georgia  Known to be about 31% G in one study.   Among the 24 G men composing this 31% group, four meet the author's criteria for likely being part of the U8* cluster.  Among the locations in the Caucasus, Georgia seems to have the closest genetic link to U8* cluster persons.  Another subgroup contains men closely related to the Kabardinians and Lezginians who live north of the Caucasus. Within Georgia is the area called South Ossetia which wants to be independent.  The Caucasus study included a large group from there. For some reason these are not in the YHRD database, and none were reported as G persons.  However, they also were never checked for the G mutation in that study.  So the proportion of G persons in South Ossetia is an important omission.  It is difficult to believe it is zero.

There is mention in the study of the Gulf of Oman in 2007 (see Cadenas in bibliography) that Dr. Regueiro has 48 unpublished samples from Georgia.  Again, it is unknown what areas were sampled, but this sample has a higher percentage of haplogroup G.  One has to deduce the G percentage from a pie chart, and that percentage seems about 60-70%. 
>Armenia   Known to be about 11% G.  Among the 11 G men composing this 11% group, none meet criteria for being U8* cluster persons.   A great diversity of G DNA profiles seen, such as in Turkey.  There might be some bias toward the profiles seen among the Kabardinians north of the Caucasus.
>Azerbaijan   Known to be about 18% G.  Among the 6 men composing this 18% groups, none meets criteria for being U8* cluster persons.  These 6 men are not enough to draw any other conclusions.
>Abazinia western Georgia.   Known to be 29% G in a small sample.  The three men representing this 29% group have marker values different from U8*cluster persons  However, they are consistent with the other western European G values.
>Abkhazia, western Georgia.  No G persons in 12 samples.

CONCLUSIONS
—  Georgia, south of the Caucusus, seems to have the highest percentage of genetic near-matches within the Caucasus region to northwestern Europe G persons.   Because the number is small and a minority within the G community, a deduction that Georgia is the original homeland would be on shaky ground.    

North Ossetia seems to have by far the highest percentage of G persons in the world.

The dominant cluster of the Kabardinians and Lezginians (characterized by DYS 385 of 13, 14) is also a minority within Georgia and is characteristic of much of the G in the western portion of the old Soviet Union.  The North Ossetian cluster is characterized by DYS 389 of 11, 28 and is uncommon at any other location currently for which  samples are available.

One partial explanation for the presence of  U8* cluster persons both sides of the Caucasus may be the practice of intermarriage across the mountains by princes and princesses. (see Sulimirski, The Sarmatians , p. 198)  Also in the first millenium of the Current Era a large group of Caucasus persons was recruited to live in Georgia.



Turkey (abt. 11 percent G) 

A 2004 study found 57 G men among 523 DNA samples.   Some regional variation within Turkey was reported in this study, but there were not enough samples in each region to be statistically reliable as to regional percentages.      
Cinnioglu's study of Y chromosomes in Anatolia Turkey
Some of the marker combinations in the Cinnioglu study are similar to those seen in the nearby Caucasus Mountains and to central Greece and Macedonia and to those among the Iraqi Kurds.  It is not sure who the immediate ancestors of these men were.  During the Roman Empire, one group of Alans was responsible for raids into today's Iran, and this Turkish group may be the one if the Alans were mostly G persons.  Some of the G's in Turkey might also be descendants of Alans hired by the Byzantine emporers at times. They might also be descendants of the Cimmerians who were described as arriving in Anatolia when expelled from the northern Caucasus Mtns. in the 700s B.C.E. by the Scythians, to whom they might have been related.  The Scythians were also described as cavalrymen speaking a Persian language, a description applied also to Sarmatians.

A special study of Kurds who live primarily in southeastern Turkey found 0-4% G persons depending on the location.  The non-Turkish test participants lived in countries along the border adjoining that area of Turkey. (Nasidze, 2005)  Those Kurds in the Caucasus area resettled there mostly in the World War I period.

Only 1 of the 57 Turkish men meets criteria for being U8* cluster persons.  Most of the men fail to match by at least 3 markers meaning the relationship to the U8* group is remote.  The Turks are characterized by an usually large percentage of 21 at DYS 390 — almost half the total.  This same 21 pattern is seen among the Iraqi Kurds where one study showed one very common haplotype among them.  A study by King et al. (2008) found that a significant proportion of the haplo G men tested by Cinnioglu are also M406+.  This new SNP has not been properly classified, but early indications are that it might be found primarily in Turkey and Greece.


Southeastern European Countries  (abt. 0-4 percent G)
The following percentages of G persons in southeastern European countries have been estimated using the markers combinations found in the YHRD database: 

Albania. abt. 0-2%    There are 0 to 2 likely G men in 101 cases in YHRD.  Two men in the study have marker patterns that could belong to either G or another group.

Bosnia-Herzegovina  1-2% .   There is just 1 in 110 total samples taken at Mostar, Doboj-Banja-Luka and Sarajevo for YHRD that is highly likely G haplogroup.  There were 2 other men who might be G, but their pattern might also be that of another haplogroup.  None of these men belong to U8* cluster.  In a 2005 study of Bosnia-Hezegovina, 2% of 256 men were found to be G persons.

Bulgaria. 4-8%.   There are 5 in 122 cases (4% of the total) at YHRD highly likely to be G persons.  There are six others (4% of the total) who might be G, but their marker values overlap other haplogroups.  Unlike the situation in neighboring Romania, none of these Bulgarian men belong to the U8* cluster.

Croatia.  2-3%.    There are 3 in 150 YHRD samples taken at Zagreb highly likely to be G persons.  There is one other with simultaneous characteristics of another haplogroup who might also be G.  Just one of these Croatian men belongs to the U8* cluster.
It has been said in some sources that the Croatians, who today have their own country, claim the Sarmatians as their ancestors.  If so, the available studies do not seem to validate this conclusion, presuming that G is the signature haplogroup for Sarmatians.
Croatians -- Population Origins
Y Haplogroups in Croatian Population  This article found 4% G percentage among 451 samples, but the island of Korcula had 11% among 132 samples.  This island over the years has had a significant presence of Phoenicians, Greeks, Slavs and Venetians, among others, with no obvious source of the G.

Greece.  3-4%.    There are 7 in 248 cases likely to be G persons.   There are 4 others who might also be G persons.  Those samples from the outer islands, such as Crete, Chios and Peloponnes and the northern interior in Macedonia province seem to be much less likely to have G persons than the central portion of the country.  The patterns seen are more suggestive of those seen in Turkey than in the rest of Europe.  A 2003 study found abt. 7% G2 men among 366 Greek samples.  This latter study, which has more island samples, did not find G persons to be fewer in the islands.  A new study by King et al. (2008 - see bibliography) found that a significant proportion of the haplo G men in Greece and Crete are also M406+.  This new SNP has not been properly classified, but earlier indications are that it might be found primarily in Turkey and Greece.

Crete9%.  In the Martinez study (see bibliograpy) 16 in 168 cases in the eastern part of the island were found to be G.  Only 25% of these samples was G2a (P15+) but the remainder were not typed for other subgroups of G.  A new study by King et al. (2008 - see bibliography) found that a significant proportion of the haplo G men in Greece and Crete are also M406+.  This new SNP has not been properly classified, but earlier indications are that it might be found primarily in Turkey and Greece.

Macedonia.  2% .   There are 3 in 149 cases likely to be G persons.  None belong to the U8* cluster.

Serbia — seemingly not represented in YHRD.

Slovenia.  2% .  There are 3 in 121 YHRD samples taken at Ljubljana highly likely to be G persons.  None belong to the U8* cluster.

CONCLUSION — There are seemingly only small percentages of G persons in southeastern Europe.  None of the countries have significant numbers of persons belonging to the U8* cluster.  Greek and Macedonian test participants seem most closely related to Turkish G persons.


Poland and Western portion of old Soviet Union  (less than 1 percent G)
The following percentages of G persons in these countries have been estimated using the markers combinations found in the YHRD database: 

Ukraine and Western Russia.  1%.    There are 3 in 318 samples in YHRD taken at Kiev, Novgorrod and Moscow that are likely G persons.  There is also one other who might be a G person within these samples.  None are part of the U8* cluster.  And a quick scan of new western Russian samples available in YHRD in early 2007 failed to find likely U8* cluster samples.   The Ukrainian samples share many similarities with samples from the northern Caucasus region.  There is also a listing of 129 men in YHRD who are Old Believers of the Russian Orthodox Church, but living in Bialystok, Poland.  Their families presumably came from Russia.  None of these Old Believers seem to be G persons.  In addition, a 2005 study in Genetika  found a 1.5% G haplogroup rate among 68 Byelorussians.

Belarus.  1%.   The samples in YHRD from Belarus lack several important markers and cannot be used for comparisons.  However, Byelorussian men at Bialystok, Poland, were tested and 2 of 157 men are highly likely to be G persons.  One of these men belongs to the U8* cluster.

Estonia. 0%.   There are no obvious G persons in YHRD in a sample of 133 men tested at Tartu. 

Latvia.   1% .   There are 2 in 145 YHRD samples taken at Riga that are highly likely to be G persons.  None of these are part of the U8* cluster.

Lithuania.  2-3%.   There are 3 in 157 YHRD samples taken at Vilnius that are highly likely to be G persons.  There 2 other men who might be G persons.  None of these men are part of the U8* cluster.  They seem most closely related to the Kabardinian persons north of the Caucasus Mtns.

Poland   2% .   There are 34 in 2,110 YHRD samples taken at Bialystok, Bydgoszcz, Gdansk, Krakow, Lublin, Suwalki, Szczecin, Warsaw and Wroclaw that are highly likely to represent G persons.   There are an additional 11 persons who might also be G persons.  Several person belong to the U8* cluster, but the values found in DYS385 are most typical of the Kabardinians of the northern Caucasus Mtns.  The Sarmatian remnants spoken of throughout the Middle Ages in Poland might be descendants of the Antae tribe of Sarmatians if the Sarmatians were predominantly G.

Tajikistan  There is mention in the study of the Gulf of Oman in 2007 (see Cadenas in bibliography) that Dr. Regueiro has 24 unpublished samples from Tajikistan.  There are no observable G samples on the related pie chart provided for Tajikistan.

Uzbekistan and Kazakhstan  A 2001 study by Karafet et. al. found among 54 Uzbekistan samples about 4% G, and among 30 Kazakhstan samples, about 12% G.   Several Uzbek samples in a private database are similar to samples in my mostly English clade # 4.  [see my G clade page]  But one of the these was a Crimean Tatar.  [Large number of Crimeans were removed from there by Stalin, and are returning there in recent years.]

CONCLUSION — Poland and the western part of the old Soviet Union have marker values typical of the Kabardinian areas north of the Caucasus Mtns. rather than the countries to the west.  Samples from the other areas are not available.

Southern Siberia
The 2005 Derenko study of multiple groups of southern Siberia along the China-Mongolian border
found less than 1% of G in three populations: Altaians, Buryats, and Tuvinians.  It is unclear whether there is any possibility these located G persons might be descendants of persons banished to Siberia under various Russian/Soviet administrations.  No G persons were found in samples taken in Mongolia, and among Teleuts, Khakassians, Shors, Toijns, Sojots, Kalmyks, Evenks and Tofalars.


East Central European Countries
The following percentages of G persons in these countries have been estimated using the markers combinations found in the YHRD database: 

Romania.  abt. 4-5%  There are 16 to 18 likely G men among 375 cases in YHRD.  The rate is higher is several specific areas of Romania than in others. The sampled areas seem to be entirely in the center of the country.  Sample sites listed as (1) Romania, (2) Lunca De Sus, (3) Corund and (4) Miercurea Ciuc.  The U8* cluster is in the near majority, as represented by 8 of the 16 likely men, a U8* pattern seen also  in Britain.

Moldova.  abt 4%   In a 2006 study of the Turkish-speaking Gagauz of Moldova, Nasitze et al. found that this group and their neighbors in Moldova were abuot 4% G among 100 total samples.

Hungary.  abt. 2%.   There are 193 cases from central Hungary at Budapest  in YHRD.  Of these, 6 men (abt. 3%) are likely G persons with only one included in the U8* cluster.  Budapest is just to the west of several provinces settled by a large group of Alans in the Middle Ages.  It is possible that a group of about 22 men (abt 11% of the total) in the Budapest sample are also G persons.  The DNA pattern in question among this latter group is also seen in I1a persons.  Without additional testing it is not possible to determine which haplogroup is represented by these men.  Of particular interest, most of these DNA patterns have DYS 385 values of 13,14, which are typical of that seen in the northwestern Caucasus among men determined by SNP testing to be G persons.  However,  one study found 10 percent of Hungary was I1a, without reporting the specific marker patterns.  This 13,14 pattern is definitely missing in the southern Hungary group at Szeged, which argues somewhat in favor of this 13,14 pattern at Budapest being an Alan signature originating in the settlements east of Budapest (if the Alans were predominantly G).  On the other hand, if the 13,14 men are omitted, no likely I1A persons would be present among the 193 Budapest test subjects.  This latter situation would be inconsistent with the cited study of I haplogroup as it pertained to Hungary.   Testing of men from that eastern Hungarian Alan region would likely resolve the question, but nothing seems available at present. 

Also available are the 100 men in YHRD tested at Szeged in southern Hungary.  One man (1% of the total) is likely a G person, but the pattern is not part of the U8* cluster.  Several other men are possible Gs, but I1a is just as likely.

Slovakia — not apparently represented in the YHRD database.  

Czech Republic 4-6%  —
There are 10 likely G men (4% of the total)  among 252 YHRD samples taken in central Bohemia.  Also, an additional 5 Czechs (2% of the total) might be G persons with closely shared marker patterns with other groups making it difficult to distinguish the correct haplogroup.  None of these men belong to the U8* cluster.  A specifc Czech study found among 257 samples that .8% were plain G and 4.3% were G2a [then called G2].

CONCLUSION — Romania  shows up as the only location in eastern Europe with high percentage of matches to the U8* cluster.  This might suggest that Romania is today the location of the remnants of the ancestral group for many of the U8* cluster G persons.  The sample size of G persons is not as large as would be desired for a statistically reliable conclusion.


Germany, Austria, Switzerland (abt. 5 percent G)
The following percentages of G persons in these countries have been estimated using the markers combinations found in the YHRD database: 

Germany.  4-5%  There are 215 likely G men (4% of the total) among 5,343 YHRD samples taken at Berlin, Chemnitz, Cologne, Dresden, Düsseldorf, Freiburg, Greifswald, Halle, Hamburg, Leipzig, Magdeburg, Mainz, Muenster, Munich, Rostock and Stuttgart.  Also included in this collection are men from a group of German Sorbs, a distinct group with Slavic origins.  Also, an additional 63 Germans in YHRD (1% of the total) might be G persons with closely shared marker patterns with other haplogroups making it difficult to distinguish the correct haplogroup.  There are no dramatic differences among the regions of Germany as to the percentage of likely G persons.  Freiburg and Stuttgart in the southwest have a slightly above average  4.7%, and Munich in the southeast is slightly above average at 6% G persons.  Only 51 of the likely 215 G men belong to the U8* cluster.  The G people in Germany seem to be a conglomeration of G profiles from all the surrounding countries.  The barbarian invasions prior to 1500 yrs B.P. could have helped spread the genetic profiles, and there has been in-migration since into Germany.  For example, northern Germany took in up to a half-million Protestant Huguenots fleeing from France in earlier centuries as well as a large group of Protestants expelled from Austrian Salzburg.  There were also Turkish workers who came to Germany after World War II, and G has a higher percentage in Turkey than Germany.
 
Austria  8-10%?    There are 22 likely G men ( 8%) among 261 YHRD Austrian samples taken in the Tyrol, at Graz and Vienna.  This is the highest percentage of G persons in any country west of the Caucasus Mtns.  Almost all these likely G men actually were found among the Tyrol samples in the western part of the country.   Since this area actually represents less than 10% of the population, the G percentage is all of Austria could be as low as 4%.  Also, an additional 6 Austrians in YHRD (2% of the Austrian total) might be G persons with closely shared marker patterns with other groups, making it difficult to distinguish the correct haplogroup.  Like its German neighbor, the G profiles are quite diverse.  The same marker combinations are seen as in Germany.  The U8* cluster is seen in 8 of the 22 men though the combinations are atypical.

Switzerland   5-6% .   There are 17 likely G men ( 5%) among 346 YHRD samples taken at Lausanne, Bern and an unstated location.  Also, an additional 5 Swiss in YHRD ( 1% of the Swiss total) might be G persons with closely shared marker patterns with other groups, making it difficult to distinguish the correct haplogroup.   Three of the 17 men belong to the U8* cluster.  The total number of G men is too small to make other conclusions as to origins. 



Scandinavia (abt 2 percent G) 
The following percentages of G persons in these countries have been estimated using the marker value combinations found in the YHRD database:   In Scandinavia, there are many persons with I1a haplotype, and some marker combinations are difficult to distinguish from some G combinations.  However, very few of these are likely to be G persons.  Only two of the Scandinavian men in YHRD are part of the U8* cluster.

Sweden.   2-3+%.   There are 18 likely G men among 718 YHRD samples taken at Blekinge, Gotland, Östergotland/Jönköping, Skaraborg, Värmland, Västerbotten, Uppsala and also at an unstated location.  There are 35 additional men in this sample (4 % of the total) whose combinations are closest to G persons, but logically most are probably I1a persons whose scores are very close to the G scores in each instance.  Studies that checked specifically for the G mutation are necessary here with so much ambiguity, and a 2006 study of Swedish men found 10 G men among 343 sampled. (3.4%)

Norway.   2%.   There are 5 likely G men among 300 YHRD samples taken from multiple areas of Norway.  There are 19 additional men in this sample (3 % of the total) whose combinations are closest to G persons, but logically most are probably I1a persons whose scores are very close to the G scores in each instance.

Denmark.  1%.   There are 3 likely G men among 247 YHRD Danish samples.  There are 7 additional men in this sample (3 % of the total) whose combinations are closest to G persons, but logically most are probably I1a persons whose scores are very close to the G scores in each instance.

Finland.  2%.   There are 7 likely G men among 399 YHRD Finnish samples.  There are  2 additional men in this sample (1 % of the total) whose combinations are closest to G persons, but logically most are probably I1a persons whose scores are very close to the G scores in the Whit Athey haplogroup calculator in each instance.  A 2006 study covering only the Österbotten area found 2 G persons among about 40 men there (5%).

CONCLUSION —  The Scandinavian G men tend to have their nearest genetic matches in other Scandinavian countries, and a high percentage have a DYS390 value of 23.  Most of the possible G marker combinations in YHRD for Scandinavia seem rather to be accidental similarities with the very common I1a haplogroup markers.  Many of these unresolved Scandinavian group designations, for example, have DYS19 = 14, which is a very uncommon finding among confirmed G persons.    There are several U8* cluster marker sets in the Y-Search database from Scandinavia, but the YHRD sample set is much more random and only contains two U8* cluster persons among the 33 likely G men.  A Norwegian study not yet listed here suggests the U8* cluster persons are much more common there.  A  minority of G persons in Scandinavia also have profiles most resembling the northern Caucasus area profiles.  Outside of Scandinavia, most of the found G combinations cluster together mostly with German samples.   Some of these G persons may have come into Scandinavia with Huguenots and Walloon emigations.

Low Countries and France. (abt. 3 percent G)   The following percentages of G persons in these countries have been estimated using the markers combinations found in the YHRD database: 

Netherlands.  3-5%  There are 11 likely G men (3% of the total) among 371 YHRD samples taken at Zeeland, Limburg, Leiden, Groningen, Friesland and an unstated location.   Also, an additional 6 Dutchmen in YHRD (2% of the total) may or may not be G persons.  Four of the 11 likely G men belong to the U8* cluster.  It is difficult to categorize the other likely men because of the diversity.

Belgium.  2-4%  There are 5 likely G men (2% of the total) among 238 YHRD samples taken at Brussels and Leuven.   Also, an additional 5 Belgians in YHRD (2% of the total)  may or may not be G persons.  The number of men found is too small to make any valid conclusions, but 2 of the 5 likely G men belong to the U8* cluster.

France.   2½-3%  There are 8 likely G men (2.5%) among 333 YHRD samples taken at Paris, Strasbourg and Lyon.  [Nothing available from western France.].  Also, an additional 2 Frenchmen in YHRD (1% of the total)  may or may not be G persons.  Four of the 8 likely G men belong to the U8* cluster, and the non-cluster men are too few to make a valid conclusion.

CONCLUSION — These G people might be descendants of the Alan Sarmatians and other Sarmatians the Romans recruited as settlers in northern France and Belgium AND the Alans who accompanied the Goths to southern France if G predominated among these groups.  The number of G samples is too small for valid conclusions.  It might be especially useful to have samples from Brittany where Alan allies were supposedly providing cavalry support in the Middle Ages.



British Isles (less than 2 percent G) 

Only two specific areas of England (London and Birmingham) have test results available in the YHRD database.   

In England , 8 likely G men (2% of the total) were found among 371 YHRD samples taken at at test sites in Birmingham and London.  Also, an additional 3 Englishmen in YHRD (1% of the total)  may or may not be G persons.  Only two of the likely G men in YHRD belong to the U8* cluster, but much larger data sets in Y-Search and Sorenson databases indicate that the true percentage of the U8* cluster in Britain is almost half the G total within the British population.

Only one man in Ireland out of 152 Irish YHRD samples represents a likely G person.  A much better study of Ireland gathered 797 Y samples from throughout the island.  They determined the haplogroups of all these men and did not find any that were G.  However, several of those not fully resolved into a specific haplogroup could be G persons.  This data for this article by Moore et. al. (2005) located in the .xls spreadsheet file listed there.

Unfortunately, YHRD has not provided test results from the more typically Celtic areas, such as Wales, Scotland and (apparently) western Ireland.  Two of the three sites (from other data) seem to indicate smaller percentages of G in these two sites than in England, making it likely that the true percentage of G overall in the British Isles is less than 2%.  The author has here in this narrative not included specialty studies in YHRD which provide data on Chinese, Indian and Carib ethnic groups in England.
 
A 2002 study by Weale  et. al.  found only one case of U8* cluster marker values among 313 men they tested in a belt across central England that included northern Wales. (see table in the Weale study)  This result probably overstates the actual rate in that region because they did not make use of several of the faster-mutating and more characteristic G basic markers as part of their marker set. 

CONCLUSION —  G haplogroup within Britain has one of the lowest percentages in Europe.  The conclusions about this population are covered in the first page of this site.



Italy (abt. 5 percent G)

There are 89 likely G men (5% of the total) among 1,645 YHRD samples taken at or in Bologna, Venice, Tuscany, Umbria, Puglia, Marche, Liguria, Lombardy, Latium and Emilia Romagna, as well as the Sicilian towns of Caccamo, Sciacca, Piazza Armerina, Alcomo, Santa Ninfa, Mazara del Vallo, Ragusa, Pantelleria, Trapani, Troina and an unidentifed location.   Also, an additional 20 Italians in YHRD (1% of the total) may or may not be G persons. 

Because Italy is a lengthy country, the regional percentages are of particular interest.  Sicily in the far south has 4% likely G men.  Puglia in the southeast heel of the Italian boot has 6%.  Latium and Umbria in the center have 5%.   In the northwest, Tuscany, Liguria and Lombardy have 5.5%.  In the northeast, Venice, Bologna, Marche and Emilia Romagna have 8%.

A 2003 study of 524 men in small Italian towns found G2a [then termed G2] percentages slightly higher than mine.  However, a 2007 study with 699 samples taken all over the Italian peninsula found 75 G men, representing 11% of the total -- with similar G percentages found throughout the peninsula. 

The maximum percentages of likely G Italian men who are near to the U8* cluster are as follows:  Sicily (39%), Puglia, southeast heel (0% in a small sample), Latium and Umbria in the center (36%), the northeast (12%), the northwest (22%). 

Sardinia was the subject of a separate study in which no marker values were reported, but the haplogroups were tested.  This 2003 study by Zei et. al. in the European Journal of Human Genetics , found 28 of 202 Sardinian men (13.8%) were G persons. This is  higher than in the rest of Italy.  Sardinia has three distinct regions, and there has been some cross migration among the regions.  Zei noted that haplogroup G was found in higher than expected numbers in the northern end of the island.   About 25% of the population in the north is G, and 65% of the G is found in the north.  The other Sardinian haplogroups do not have this distribution.  The north is the area invaded by Catalan-speaking groups in 1372, pushing back the native Sardinians in that area.  I originally thought they could account for this unusual G percentage, but further information seems to suggest the occupation was restricted primarily to one town.  Today the Catalan-speaking persons are overwhelmingly residents of that town, and the Sardinian researchers did not specifically sample this town.  So this odd percentage of G seemingly must have its origins in Roman times or earlier due to lack of other known colonization since then.  There are Roman ruins in the north, and it is known that the Romans exiled individuals and groups, including Jews, to the island.  A single 7-marker Sardinian result is available from an unpublished research project, but the values are not typical of any known cluster within haplogroup G.

CONCLUSION —  Although the percentage of the U8* cluster is unusually high in the southern part of Italy, these men do not seem genetically as close to the U8* cluster persons in northwestern Europe as are those in Romania because the specific marker variations  in Romania are more similar to those in Britain.   Those G persons in the north of Italy are candidates for being descendants of the Alans and other Sarmatians the Romans allowed to settle there in the late Roman Empire.  Some Sarmatian slaves also came with the Germanic Lombards in their occupation of mostly northern Italy.  These comments presume these Sarmatians were predominantly haplo G, which is not proven.


Iberian Peninsula (abt. 4 percent G)   The following percentages of G persons in these countries have been estimated using the marker combinations found in the YHRD database: 

Spain.  3%.   There are 39 likely G men (3%) among 1,486 YHRD Spanish samples.  There are 5 additional men in this sample (less than 1% of the total) who may or may not be G persons

Portugal.  5%.    There are 57 likely G men (5%) among 1165 YHRD Portuguese samples.  There are 6 additional men in this sample (less than 1 % of the total) who may or may not be G persons. There are 9 men with the values of 12/16 for DYS 385.  There are only four other persons throughout Europe with this finding.  The DYS19 value of 16 is also found in unusually high frequencies there. 

The maximum percentages of likely G Iberian men who possibly belong to the U8* cluster are as follows:  Portugal (5%), Spain (20%)  So far no one belonging to the U13 cluster has been located within these two Iberian countries though it is present in most other parts of western Europe.

In a 2005 study, of 168 Basque men from the Gipuzkoa, Biscay, Alava & Navarre areas, only 1 in 168 were G, that being 1 G2a [then termed G2] man who was not G2a1 [then termed G2a].  This study also updated a 2003 study of Iberia, in which of 692 men 30 were now found to be haplogroup G (4%).  Of the 30, 28 were G2a [then termed G2], 1 was G2a1 [then termed G2a] and 1 was G but not G2a [then termed G2].

CONCLUSION —  In the most likely explanation, most G persons in Spain are perhaps descendants of the Alans who were Goth allies who expelled the Vandals from the Iberian peninsula if the Alans were predominantly G persons.  The G persons in Portugal are perhaps similarly mostly descendants of the Alans who occupied Lusitania (mostly Portugal) during the Vandal occupation of the peninsula.  Portuguese G persons have an unusual percentages of 12,16 values at DYS385.  This finding is almost non-existant elsewhere.  12, 16 may have resulted from a founder effect, where one man with an atypical value passed it on to a large number of descendants in that one area.  


Iran
There are only about 5 G samples available from central Iran.  (see corresponding Nasidze article in bibliography) They are much closer to the DNA profiles seen in western Europe than those found today in the northern Caucasus--if this pattern holds up in a larger sample.  The U8* cluster seems to be present in Iran in unknown quantities.  

A summer 2006 study of Iranian Y chromosome haplogroups indicates that haplogroup samples from central Iran in general show most similarities with patterns in the Caucasus region and Uzbekistan.  In contrast, in their new samples from north and south Iran, the haplogroup patterns were more similar to those seen in Turkey and Pakistan.  This was not a generalization specifically applied to G distributions and may not be true for G.  This study, however, is one of the few available that checked for subgroups of G.  Almost half the samples in southern Iran were G1 haplogroup, apparently the highest known percentage of  G1 among G populations in the world.  There was no haplotype information in this study, and the only useful information for the G subject area is that G2a [then termed G2] predominates in north and south Iran (as seemingly everywhere else in the world) and that G1 is seen in unusual frequency in south Iran.  Nasidze (see bibliography) has made 3 studies of Iran but has failed to test for anything other than general G (M201), and he does not make his haplotypes available on a timely basis.  The 2008 article summarizes the G percentages in all 3 studies, noting 22% G among the Gilaki (50 samples), 14% among the Mazandarani (50 samples) and 8% among the Bakhtiari (53 samples), which is significantly higher than among Arabs of southwest Iran and the general population of central Iran.  [The Gilaki and Mazandarani live in the South Caspian area]


Middle East
A 2005 study of Jordan Y-chromosomes also included in the authors' table 1 a listing of G percentages in other regional studies.  The testing was only for G (M201) and not for the subgroups.  The results showed the following percentages:
Jordan -- 4% in 146 samples
Oman -- 3% in 121 samples
Iraq -- 3% in 203 samples
Lebanon -- 3% in 104 samples
Syria -- 3% in 111 samples
Palestine -- 3 % in 143 samples.

A 2004 study (see Shen in bibliography) found among the following Israelis:
  no G among 12 Samaritans [an Israeli ethnic group]
  6 of 20 tested Moroccan Jews were G2.  
  15 of 20 Palestinians tested were G2
  2 of 20 Libyan Jews were G2
  1 of 20 Yemenite Jews were G2
  2 of 20 Iraqi Jews were G2
 
And a 2007 study of Qatar, United Arab Emirates and Yemen (see Cadenas in bibliography) found a small amount of G in these countries.
In Qatar, 2.8% of 72 samples were  G2.
In the UAE, 1.8% of 164 samples were G2, 1.8% were G1 and .6% were G1a.
In Yemen, 1.6% of 62 samples were G2.

The findings in regard to the UAE make it the apparent 3rd largest known locale for G1
percentage in the world, but the numbers are so small this probably does not reach
criteria for statistical significance.


North Africa

Egypt
Egypt -- 10% in 147 samples taken at Cairo and Tanta.  Info from the data accompanying Luis's 2004 article (see bibliography)
He indentified 13 G persons in Egypt, all of them G2a [then termed G2].  There is a great similarity among most Tanta samples.

Berbers
Describing them only as North African Berbers, a
2005 study found 2 of 75 men as G (3%).  Both of these men were G2a [then termed G2] but not G2a1 [then termed G2a].  A 2002 study found 2 of 49 Arab Moroccans as G (4%), and likewise 5 of 64 Berber Moroccans as G (8%).  The authors refer in this latter study to G as # 54, which corresponds to M201 mutation in another table.

Tunisia
The Alans and Vandals had their headquarters originally in North Africa at Carthage.  This town is now in Tunisia.   There are 246 Tunisians listed in the YHRD database, including 30 Berbers, 131 Anadulisian Arabs and 31 samples from Zriba, and 54 from Tunis.  None of the these men have any DNA pattern resembling the G patterns seen in Europe.



 Pakistan
A 2006 study of three populations in northern Pakistan by Firasat et al. (see bibliography) found that among 97 samples among the Burusho 1% were G; among 44 samples among the Kalash 18% were G; and among 96 samples among the Pathan, 12% were G.  They tested only for the M201 SNP marker and not for subtypes of G.  An earlier 2002 study of Pakistan by Qamar et al. which seemed to include G haplotypes in the authors' group 8 did not find so many G persons among the Kalash in a similar 44 sample universe.  Sengupta et al.'s 2006 study of the general region found (1) G1 person among 75 Pakistani samples.  He was among the Branhui of S. Parkiston.  They also found (2) G2c [then termed G5] persons among these 75 samples, one among the Burusho of S. Pakistan and one among Pathan of the north.  These same researchers found (8) G2a [then termed G2] persons among these 75 samples.  Five were Kalash people from the north, and three were among the semi-Dravidian Brahui of the south.  There were only 19 Kalash samples.


East and South Asia
In the 2006 study by Michael Hammer et. al pertaining to Japan (see bibiliography) is contained in the supplementary material a listing of the G percentage in the following populations:

Zero percent
Japan - 0% in 259 samples
Southern Han of China - 0% in 40 samples
Korea - 0% in 75 samples
Taiwan - 0% in 132 samples
Vietnam - 0% in 70 samples
Philippines - 0% in 48 samples
Indonesia - 0% in 80 samples
Oceania (native peoples) - 0% in 209 samples
Tibet - 0% in 105 samples
No G found among the Manchu and Manchurians, Evenks, Evens, Oroqens, Tujias, Yizus, Miaos,
         Yaos, Yuangs and Shes.

Some G in population
Northern Han of China - 2.3% in 44 samples
Buryat people of northeastern Asia - 1.2% in 41 samples
Malay people - 6.3% in 32 samples
Uygur of central Asia - 4.5% in 67 samples
Altai of central Asia - 1% in 98 samples
Mongolia - 0.7% in 149 samples
India - 1.5% in 403 samples  [an unpublished study also found (1) G2c man in northwestern India]
Sir Lanka - 5.5% in 91 samples
