A serological analysis of the Bhoksa: a scheduled tribe of Uttar Pradesh.

ABO blood groups, subgroups, M, N and Rh blood types were studied among Bhoksas of Dehra Dun district in Uttar Pradesh. Bhoksas are characterized by high A (33.33%), MN (58.16%), Rz (8.85%), R" (7.86%) and moderately low R1 (43.77%). The present sample does not show differences from the Bhoksas of Nainital but remains differentiated from Majumdar's sample so far as ABO blood groups are concerned. The present Bhoksas also remain undifferentiated from many Mongoloid and other populations of Eastern and Western Himalayas with respect to certain Rh chromosome frequencies. On the whole it is difficult to subscribe to, or reject, Bhoksas' claim of Rajput ancestry. Their differences with Indian Mongoloid populations namely, Bhotias and Tharus suggest that they might not belong to Mongoloid stock.
