Summary

A total of 469 individuals belonging to 4 endogamous groups (Brahamins, Rajputs, Doms and Tharus) from the Kumaon region (North India) were tested for Hp, Gc, Gm and Inv systems.

The frequency of the Hp1 allele is low (0.130–0.220) in all 4 groups as in the case of other Indian populations. The absence of the Gm5 allele and high frequency of Inv(1) (49.34%) confirm the Mongoloid affiliations of the Tharus. Brahamins, Rajputs and Doms possess 4 alleles (Gm1, Gm1,2, Gm1,5 and Gm5) at the Gm locus and the frequency of Gm1,2 allele is very low (0.067–0.106) for these groups. The frequency of Inv(1) for Brahamins (19.61%) and Doms (22.78%) lies within the range of variation of European populations. Rajputs, however, show a higher Inv(1) frequency (38.76%).

Genetic distances calculated with the help of Hp, Gc and Gm systems demonstrate similarity between Brahamins, Rajputs and Doms and a deviant position for the Tharus.
