Article: Genetic differentiation and population structure of some occupational caste groups in Uttar Pradesh, India

Abstract Phenotypes and gene frequencies of 24 genetic markers (9 blood groups, 11 red cell enzymes, and 4 serum proteins) were investigated in 5 occupational caste groups (Brahmin, Khatri, Vaish, Kayastha, and scheduled castes) and 1 religious group of Muslims in Uttar Pradesh, India. This is the first extensive genetic study in Uttar Pradesh that establishes the range of genetic variation in different endogamous groups. The extent of genetic variation among different occupational caste groups is low, and only two genetic systems (C3 and ACP) showed heterogeneity. The genetic affinity analysis showed an unexpected close affinity of scheduled castes with the Khatri. This observation ...
