Natural Selection Intensity in Settibalija - A Mendelian Human Population from South India

The selection intensity indices were computed based on the demographic information pertaining to fertility and mortality among Settibalija, an endogamous Mendelian population of Andhra Pradesh, South India. The total fertility and mortality indices are slightly lower than other Andhra populations studied earlier. In the present caste population, the selection is manifested primarily through differential fertility rather than mortality, which is a not deviation from general trend. The results are discussed in the light of earlier studies on some caste and tribal populations inhabiting Andhra Pradesh, South India.
