The Bengali y-dna from BEB samples looks very diverse.
Goes to show Bengali ethnogenesis was complicated. :D

All 3 belong to H-M82 (specifically SK-1225 clade).

Pretty much everything found in Bengalis. R-Z94 and H-M82 dominate.

Does anyone have any thoughts on how Q-Y1150 made it to Bangladesh? My parents are originally from Bangladesh, and I got Q-Z36070:


According to yfull, TMRCA = 3600 years, and there are 2 Bangladeshis (including me). In addition, there is a sample from Turkey.

I also noticed that there were a number of Pashtuns who got Q-Y1150. Could Q-Y1150 have been carried by Afghans to Bangladesh in the last several hundred years?

Thanks so much for your help!

I learned from another user that the Q-Y1150 found in Pashtuns comes from a different subclade, so it isn't the same Q-Y1150, and can't have been carried by the Afghans found in that study. Still puzzled about how this strand of Q got to Bangladesh. I guess I might never know until we get more samples. Thank you.
