A sample of high-caste Hindus from Bengal, India, was found to be polymorphic for five Gm haplotypes, including Gm 3;5, Gm 1;21 and Gm 1,2;21 which are common in Caucasians, and Gm1,17;5 and Gm1;13,15,16, both of which may indicate affinities with populations of central and/or southwestern Asia. The frequencies observed in Bengalis are intermediate between those seen in Hindus from northwestern India and from southern India.
