A genetic study of the Konda Kapu tribe of coastal Andhra Pradesh, South India.

Phenotype and gene frequencies of two blood group and four red cell enzyme systems were examined in a Konda Kapu tribal sample of Coastal Andhra Pradesh, South India. The gene frequencies for these systems in Konda Kapus indicate the middle range values for Andhra Pradesh tribal populations, excepting the ADA and Rh(D) systems, where extreme range values are found. Further, gene flow is indicated between the Konda Kapus under study and Plain Kapus, a neighbouring caste population by calculation of Fi estimates.
