Genetic diversity of PTC taste sensitivity among tribal and caste populations of Andhra Pradesh, India.
The present paper reports the variability of PTC taste sensitivity among eight endogamous tribal populations inhabiting the Eastern Ghats of North Coastal Andhra Pradesh. It was compared with the genetic diversity of PTC taste sensitivity among tribal and caste populations of Andhra Pradesh. The tribal and caste groups present a relatively high genetic diversity, of which a major proportion is due to genetic differences within populations rather than that between populations. Castes show a higher heterogeneity than tribes, the difference being significant. The high genetic diversity found among Andhra populations may be attributed to social stratification and the practice of strict endogamy.
