U2b2

[surbakhunWeesste]

I was looking for studies done on U2b2. Where is it most frequently found and where did it originate? Is it Central/South Asian?

U2b is one of the three sister clades of U2 found all over south asia . I dont know where it originated but currently it is not found in places outside of south asian influence

Not sure of any studies, but here are a bunch of samples from GenBank.

U2b2a is mostly found in India and Tibet, U2b2 is mostly found in India and Pakistan (there is one sample from each group from Punjab), and a few samples from other regions, including Thailand and South Africa, and samples from Sri Lanka and Saudi Arabia. The South African sample is pre-U2b1 (i.e., between U2b and U2b1) and represents a very ancient branch, so it's uncertain where it originated. Possibly a South African person with South Asian ancestry? It would be very helpful to have more U2b full sequence samples. Anyone who tested at 23andMe can also send me their mthap extra mutation list and I'll compare with my database of U2b FMS samples.

hmm. Thanks, I found this link where it was found in Kazakhstan, this made me wonder how did it arrive there?

All the Central Asian stan countries do have some south asian specific mtdna . So it is not much of a surprise

Could be!
You stated earlier "south-Asian" influence with respect to u2b/u2b2, does Kazakstan have significant South-Asian influence?

There was a huge slave market in Uzbekistan in the 1700's where captured Indian slaves were taken, its possible some slaves made their way up to present day Kazakhstan.

That could mean more mtdna(s) likely thought to be of South-Asian origin should show up around there. Someone wrote somewhere u2b2 was pretty frequent in Kazakstan, can't find a legit source. Also, slave market has to do with lower castes! esp. in the 1700's?! wonder about the population where u2b2 within the South-Asian population. I just read an article where u2b2 was found in Kerala Jews. Its common in my maternal ancestral lineage amongst Kandahari Pashtuns, I checked another article where Ghilzis were found with u2b2. Its getting interesting.

U2 was found in kostenki man, in Western Russia. It probably originated east of that region and some subclades(mainly U2b2) went so south and south central Asia either with ANE/WHG-UHG migrations or other steppe migration while other subclades stayed in Europe.
