title: Gene differentiation at the ABO locus in twenty castes and twenty-two tribes of Andhra Pradesh, India.
abstract: Using gene frequency data for the ABO locus so far available, gene differentiation and gene identity between 20 castes and 22 tribes of Andhra Pradesh were determined. The interpopulation gene diversity is 1.4 and 1.6% of total genic variation in castes and tribes, respectively. Difficulties in interpreting genetic diversity using just one genetic system is discussed.
