| Haplogroup G-FGC7535 (G2a1) | |
|---|---|
| Possible time of origin | about 3,000 years BC |
| Possible place of origin | possibly South Caucasus region |
| Ancestor | Haplogroup G2a |
| Descendants | G2a1a |
| Defining mutations | FGC7535/SK1106/Z6552 |
Haplogroup G-FGC7535, also known as Haplogroup G2a1 (and formerly G-L293),[1] is a Y-chromosome haplogroup. It is an immediate descendant of G2a (G-P15), which is a primary branch of haplogroup G2 (P287).
G2a1 has an extremely low frequency in almost all populations except parts of the Caucasus Mountains.
In 2017, the SNP L293 was replaced by FGC7535, SK1106 and Z6552 as the defining SNPs of G2a1, due to the technical difficulty in testing for L293.[1]
