Результаты проекта снип-тестирования субкладов I2a на сегодня
http://www.familytreedna.com/public/I2aHapGroup/default.aspx?section=newsWhat have we learned thus far from SNP testing?
There have been six new SNPs discovered from the "Walk Through the Y" SNP searches by I2a donors: L158, L159, L160, L161, L178 and L233.
(1) L158 is derived (positive) for those testees who are also derived for M26. It is downstream from P37.2 on the branch of M26.
(2) L159 is derived for those testees who are also derived for M26. It is downstream from P37.2 on the branch of M26. Test results for I2a donors are shown as L159.1 to differentiate between I2a and other Haplogroup donors.
(3) L160 Downstream from P37.2, M26, L158 and L159. L160 is on the branch of M26. Four M26 clades are affected: M26-A, M26-B, M26-C and M26-France. L160 is ancestral (negative) for clade M26-France. L160 is derived for clade M26-C but can be either derived or ancestral for other clades M26-A and M26-B so both M26-A and M26-B clades' members should be tested for L160.
(4) L161 Downstream from P37.2, M423 and L178. L161 is on the Isles branch after it splits from Dinaric/Disles. L161 is derived for I2a2-M423-Isles (all varieties) while other M423 Dinaric and Disles clades are ancestral. L161 was removed from FTDNA order list, so we now are using I-L69 to tell whether a donor is Isles, Dinaric or Disles. Those who test ancestral (negative) for I-L69 but derived for M423 or L178, are I2a2-M423-Isles (all varieties).
(5)L178. Appears to be equal to M423. L178 is downstream from P37.2 and on the M423 branch which include Isles, Dinaric and Disles clades, so they all test derived for L178.
(6) L233 was recently discovered from a WTY of I2a*-P37.2-Western donor (myself). L233 is downstream from P37.2 and is on the P37.2-Western branch. I tested derived for M233 and have been told I tested ancestral for M26 and M423 but nothing was told to me about other SNPs. There are three clades affected: P37.2-Western, P37.2-France and P37.2-West Isles. There are currently six tests of M233 with results due Jan 10, 2010.
Other SNPs tested
P41.2 It is downstream from M423 and I-L69.2 and is on the Dinaric branch after it splits from Disles. P41.2 was tested by 24 I2a donors, all were negative. Donors tested include P37.2*, Isles, Dinaric and Disles, M26-B.
M161 It is downstream from P37.2, M26 and L160. M161 is on the M26 branch downstream from L158 and L159. There were 22 I2a donors tested, all were negative except for one. Donors tested include P37.2*, Isles, Dinaric, M26-B.
I-L69.2. Downstream from P37.2, M423 and L178 located on the Dinaric/ Disles branch after they split from Isles. Nine I2a donors tested: three Isles were ancestral, two Disles tested derived. One Din-N and three Din-S tested derived.
