                                                      G2a3b1 individuals (DYS388=13)
                                         on genetic branch 26C

The genetic branch 26C listed here is a name chosen to represent samples found along a branch of
a phylogenetic tree as created by special DNA software from Fluxus. The relationships shown on
the Fluxus network diagram are based on the various marker values of 67-marker samples with special
weighting given to the slower-mutating markers. Those persons in branch 26C will have unusually close
relationships with persons from other branches designated as 26, such as 26A. The availability of
additional samples may require renaming the branches, but persons closely related here will likely continue
clustering in future versions of the phylogenetic diagram.   Less closely related persons will tend to
move, and thus some caution has to be used in thinking of the branch listed here as anything more than
a helpful, but imperfect, way to try to subgroup G2a3b1 persons. Inclusion of samples with less than
67 markers on this page is based partially on guesswork, especially with regard to 12-marker samples.

The G2a3b1 status means the men will be positive in special SNP testing for general G (M201)
and G2 (P287) and G2a (P15) and for G2a3 (U8 or S126 or L30) and for G2a3b (L141) and for
G2a3b1 (P303)

The status of the men here with regard to the three subgroups of G2a3b1 is mixed. Earlier testing showed
that men within the DYS388= 13group are negative for U1 (G2a3b1a)  It is unknown how many men on this
page are positive for L42 (G2a3b1b) or for L139 (G2a3b1c). Being negative for all three subgroups would
constitute a group all to itself and designated as G2a3b1*. One man here (Bennett) was found negative for L42.

The YHRD database is a public database of samples collected from around the world as submitted by
scientists.    Because DYS388 was not tested, it cannot be ruled out that some belong to a DYS388=12
group such as DYS568=9. If the DYS426 value is italicized, it is only predicted, but virtually all G
persons have a value of 11 for this.

Recommended additional deep ancestry testing for men here with the interest and funds for this:

Upgrading to 67 markers for deep ancestry purposes can be useful in helping to better establish
relationships and time calculations to a common ancestor. However, we now have a large number of
DYS388=13 samples, and the full 67 markers seem to have no specific use for them for deep
ancestry subgrouping here. However, the additional markers may be useful within a surname project in
establishing family branches. By way of exception, additional Italian and Hispanic persons are needed
to upgrade to 67 markers to allow determination of when they split from their more northern cousins.

All tested persons in the DYS388=13 group have tested positive for the P303 SNP which characterizes G2a3b1.
The outcome of such testing for all the samples listed below is very predictable as P303+ and testing, in my
opinion, unnecessary.   SNP testing can be ordered as what is called the deep clade SNP test in the
haplotree section of the individual Family Tree DNA results page. P303 (G2a3b1) is included in this deep
clade test.

There is no hint that the persons on this page are positive for U1, which characterizes a subgroup
of P303 (G2a3b1a).   In earlier testing DYS388=13 samples are negative for U1. Little is known of the
coverage of the men on this page for L42 (G2a3b1b).   It is desirable that more persons on
on this page should test for it.    Little is known of the coverage of L139 (G2a3b1c) and confirmation that it
occurs within DYS388=13 persons would be desirable before additional persons test for this. These SNPs can
be ordered on the Family Tree DNA results page in the Order Tests section as an advanced test.  They will be
found at the top of the SNP list for $29US each. These tests will eventually be added to the G deep clade test.
Only one person from a surname group needs to test for SNPs as everyone else in the surname group will have
the same findings.
