G2a1a2

News for G2a1a2 persons.
There have been several important research studies in which G2a1 figured prominently. As you may be aware, G2a1 is found in a very concentrated form in North Ossetia-Alania in the central part of the Russian Caucausus Mountains.
 
 
I would like to refer you to a page I maintain on Wikipedia.
 
 
The new studies incorporated into this page confirmed what we already knew about North Ossetia -- namely that the majority of the population was G2a1. But in other Caucasus places where G2a1 was sampled, Abkhazians who live in the s.w. Caucasus were 12% G2a1. In addition 9% of Circassians in the n.w. Caucasus were, as were also a small percentage of the Chechians in the n.e Caucasus. Unfortunately no specific testing was done among the G2a men of South Ossetia (just south of North Ossetia) or in Georgia in the s.e. Caucasus. Georgia is a complicated situation because most countries consider Abhazkia and S. Ossetia part of Georgia though they are functionally independent of Georgia. And some of the early Georgia samples may have been taken in those two entities. We can recognize G2a1a marker value combinations as well represented among those taken about a decade ago in undefined "Georgia" before boundaries were so much of an issue.
 
 
These studies also provided some abbreviated marker samples, but I could not find among them any that could be basis of a new subgroup. The same groups found among our own participants from the Caucasus were found in these studies.
 
 
There are two types of general G2a1a2 men in your grouping:
(1) Those confirmed with 21, 21 for marker YCA
(2) Those just predicted 21, 21 for marker YCA.
 
 
Those of you who are the first type -- fully confirmed -- have tested everything that we have available to identify the G1a1a2 subgroup. We are regularly checking your values to see if any new subgroups can be established among you, but for now there is nothing new for you.
 
 
Those of you who are the second type -- only predicted 21,21 -- constitute a grouping which we would like to see be eliminated over the next year due to testing. The cost of ordering just the YCA marker is really modest. Only $7.20, plus a small transfer fee.
 
 
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.
