G2a1 or G2a1a

News for general G2a1/G2a1a persons.
We group G2a1 and G2a1a persons together because the SNP mutation for G2a1a is unreliable and may have been lost by one of you ancestors.
I do not think we have created any new subgroups within G2a1 this year, but 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 three types of general G2a1 men in your grouping:
(1)  Those confirmed G2a1 or G2a1a AND negative for all known subgroups
(2)  Those confirmed G2a1 or G2a1a AND not tested for all the known subgroups
(3) Those just predicted G2a1 or G2a1a.
Those of you who are the first type -- negative for all subgroups -- have tested everything that we have available to identify G1a1a subgroups.  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 -- not tested for all the subgroups -- constitute a grouping which we would like to see be eliminated over the next year due to testing.  Our G2a1a subgroups have shared marker value oddities at the YCA marker or DYS511.  And these need to be ordered.  The cost is really modest.  Only $7.20 per marker, and I think most you would have already paid the small transfer fee.
Our final type of men are only predicted G2a1a.  With the exception of Mr. Gentile, we feel there is a very high chance you are G2a1a because of the pattern of your marker values.  But there is no certainty, and additional deep clade tests would be most welcome.  Exceptions must be made for the Benedicts because one Benedict has already tested for everything, and you will have the same results.
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.
