Abstract

Endogamous populations belonging to Brahmin, Vysya, Mala, and Madiga castes of Andhra Pradesh, South India, were investigated for certain red cell enzyme and serum protein genetic markers. Frequency values were statistically analyzed to assess genetic variation among the populations. Average heterozygosity of ten loci and genetic diversity within and between the populations were calculated by using the methods of Nei. Nei's index was used to calculate genetic distances between the pairs of populations. A dendrogram was drawn adapting the modified unweighted pair group method suggested by Li, which agreed with the history of the populations.
