News for G2a3b1a2a persons

Because your L43 subgroup is so tiny, you must rely on the mother group for L43 for news.  The mother group is L497.  


Within the 1000 Genomes Project last fall I was able to extract perhaps about 100 SNP mutations found in five L497 men.  Some of these are SNPs shared by all L497 men.  There were an unusual number of these. suggesting that the L497 group existed as a small group for perhaps a millennium or more before a big expansion began.   Within all these SNPs are probably 10 to 20 that represent valid branches of the L497 subgroup.   We would like to have all of these available for testing, but Family Tree DNA will only provide tests that meet multiple criteria, and we were only able to get tests for Z725 and Z1901which likely only represent fairly small L497 subgroups.  We will continue to try to see that promising SNPs in this resource would be turned into tests.  If we can get these new SNPs as tests it will really accelerate progress in defining the movements of your L497 ancestors.


 L497 samples outside of Europe continue to be almost unheard of.   We  were particularly interested last year in a sample from the island of Lemnos off the western coast of Turkey. This island has known connections to the Etruscans.  This sample did turn out to be L497+ though it has some very eccentric marker values.  And a researcher found a sample with similar marker values from the west coast of Turkey that is also L497 -- the only Turkish sample of this category in his collection.  The question remains open whether whether these men are from an early branch of L497.  If so, this could argue for an early movement from the Turkish coast to Europe in conjunction with the Etruscans.

This year we added a new feature to the G web site that deals with the L497 subgroup.  
The purpose was to estimate the number of L497 men as a percentage in the population based on marker values.  This is an imperfect way to do this, but many of these sites do not have L497 testing, and this is the best we can do in the meantime.
 
We did not add any men to the project in the last year who are just L43.

We have divided your L43 (G2a3b1a2) subgroup  into two categories.
(1) Those confirmed L43 and negative for its L42 subgroup.
(2) Those confirmed L43 but not tested for the subgroup.

While there is nothing more that that the man confirmed negative for L42 can test, we would like to see the status of the man untested for L42 confirmed by testing for L42 for $29.

As mentioned in the general news section, if you are willing to better define your grouping, I will be glad to give individual recommendations and help. rayhbanks@cox.net.
