Selection intensities and inbreeding among some caste groups of Andhra Pradesh, India

Abstract

An attempt is made to study the interaction of inbreeding levels with other factors in influencing the intensity of natural selection. Results suggest that selection intensity values are high in the inbred and low socioeconomic groups of Madiga and Mala (1.545, 0.687). On the other hand, the non‐inbred and high socioeconomic group of Maheshwari shows low selection intensity (0.543). Contribution of mortality to total index of selection is greater in the groups of Madiga and Mala (1.059, 1.062) than in the Maheshwari group (0.204).
