Project Background:
This project welcomes anyone who has been predicted or SNP-tested as Y-Haplogroup T.
Haplogroup T (known as Haplogroup K2 until May 2008) is defined by SNP M70 and is found at low frequencies in the Middle East, Europe and North Africa.
Thomas Jefferson is believed to have belonged to haplogroup T, based on tests carried out on individuals sharing his paternal line.
For more information on T and the Jefferson family link see:

and

Project Goals:
The aim of the project is to investigate the history of haplogroup T, and so assist project members in following their personal ancestral trails.
As at May 2008 there are two subgroup SNPs for T, M320 and P77. M320 is thought to be very rare and P77 has only recently been published. The Project will investigate whether a subgroup structure for T is supported by STR marker patterns. |
Project News:
The Project was started on July 30th 2006.
8 members have joined within the first 2 days.
As at 20th August 2006 we have 21 members.
1st December 2006
The project now has 37 members.
8th February 2007
The project has 48 members including 7 with 67 marker haplotypes.
18th May 2007
The project has 62 members including 10 with 67 marker haplotypes.
2nd December 2007
We now have 83 members including 18 with 67 marker haplotypes.
May 2008
We now have 100 members! |
Project Results:
August 2006
Results have initially been organised into 3 subgroups based on STR marker patterns as follows:
"Alpha"
DYS454 = 13
DYS464a/b = 10,12
DYS389i = 12
DYS389ii = 27
DYS390 > 22
DYS392 > 13
"Beta"
DYS454 = 13
DYS464a/b = 11,13 or 11,14
DYS389i > 12
DYS389ii > 28
DYS390 = 23
DYS392 = 13
"Gamma"
DYS454 = 12
DYS464a/b = 11,11
DYS19 = 13
DYS389i > 12
DYS389ii > 28
DYS390 = 22
DYS392 = 13
The Thomas Jefferson haplotype would probably belong to the "Alpha" subgroup.
20th August 2006
Additional results have blurred the boundary between "Beta" and "Gamma". Members with characteristics of both groups have been added to "Beta" for now.
January 2007
"Beta" group has been split into two.
Beta-1 is the core of the former Beta group and roots appear to be mainly in the British Isles and Spain, so I have labelled it "Atlantic".
Beta-2 is more loosely defined but appears to have roots mainly in Central and Eastern Europe.
I have also created a "Gamma-2" group for haplotypes which show only some of the characteristics of the main Gamma group.
February 2007
Results for only 12 markers will not be allocated to a group unless there is already a 12/12 or 11/12 match in the group. Please upgrade to at least 25 markers!
Beta-1 and Beta-2 have been merged following further analysis of the group results, but a Beta-3 group has been identified with distinctive values at several markers including DYS464d GATA-H4 and YCAiiA.
Some members have been reallocated from Beta-2 to Gamma.
May 2007
The 67 marker results are giving a clearer picture of K2's structure. Latest analysis suggests an ancient split between Alpha/Beta and Gamma, then a more recent split of Alpha/Beta into 3 subgroups. I have created an "Alpha 2" cluster as one of the 67 marker haplotypes shows some similarity to the Alpha cluster but does not belong to it. The former "Gamma 2" group has been merged with "Alpha 2".
Ideally I would like at least two 67 marker haplotypes from each cluster to minimise the impact of recent mutations on the analysis. |
DNA Test Results (Alleles) for Project Members
* Haplogroups in green have been
confirmed by SNP testing. Haplogroups in red have
been predicted by Family Tree DNA based on unambiguous results in the
individual's personal page. This has been placed on this GAP page for your ease
and convenience. Please note that for any predicted results we see no reason for
ordering a SNP test to confirm the Haplogroup. if a – is in the HAPLO field then
we feel that the comparative results are not clear and unambiguous and if the
kit holder wants to know their SNP with 100% confidence they may consider
ordering a SNP confirmation test.
