South of the Caucasus:
>Georgia Known to be about 31% G in one study. Among the 24 G men composing this 31% group, four meet the author's criteria for likely being part of the U8* cluster. Among the locations in the Caucasus, Georgia seems to have the closest genetic link to U8* cluster persons. Another subgroup contains men closely related to the Kabardinians and Lezginians who live north of the Caucasus. Within Georgia is the area called South Ossetia which wants to be independent. The Caucasus study included a large group from there. For some reason these are not in the YHRD database, and none were reported as G persons. However, they also were never checked for the G mutation in that study. So the proportion of G persons in South Ossetia is an important omission. It is difficult to believe it is zero.
There is mention in the study of the Gulf of Oman in 2007 (see Cadenas in bibliography) that Dr. Regueiro has 48 unpublished samples from Georgia. Again, it is unknown what areas were sampled, but this sample has a higher percentage of haplogroup G. One has to deduce the G percentage from a pie chart, and that percentage seems about 60-70%.

>Digora, N. Ossetia-Alania, central Caucasus, S. W. Russia. Known to be 74% G. 17 of 24 of the tested men have an unusual 11/28 value for DYS 389. This is quite different from anything found in western Europe, but there are a few cases of this combination in eastern Europe. It is suspected, but not proven, that these men are G2a1. Among the remaining 7 Digora samples, three men are probably U8* cluster persons. The N. Ossetians claim to be remnants of the Alans, but they are genetically different from the groups in western Europe who were also called Alans.
>Ardon, N. Ossetia-Alania -- central Caucasus, S. W. Russia. Of the 28 tested men, it is known 21% are G. None are close matches to U8* cluster persons. There are two in the Ardon group who have the 11, 28 (at DYS 389) that predominates in Digora, but the sample size is small, making valid conclusions difficult.
>Alagir, Zamankul, Ziga, N. Ossetia-Alania, central Caucasus, S. W. Russia. In a second study by Nasidze, he found 51 additional G samples among 70 total samples. These represented 75%, 61% and 60% respectively of the total men sampled there. These haplotypes are displayed at the Whit Athey G website, but the 51 are several more than would be expected. Did the author add a few? The 11,28 (at DYS 389) is again extremely common at these locations and probably respresents G2a1a persons
