Gene differentiation in four subcastes of Brahmins from Visakhapatnam, Andhra Pradesh.

Blood group (ABO, MN, Rh, CcDEe) polymorphisms are reported here for 4 strictly endogamous subcastes of Andhra Brahmins. The coefficient of gene differentiation calculated from the gene frequencies is 0.87% demonstrating that only a small fraction of the total gene diversity is attributable to the differences between subcastes. In spite of the strict endogamy for the past 10-14 centuries, 99.13% of gene differentiation exists within the subcastes.

Birth weight and natural selection.

Differential mortality as a function of birth weight was studied in newborns up to the 1st week of life in Visakhapatnam, Andhra Pradesh (India). It was found that both selection intensity and selective deaths were higher than in other studies. Furthermore, in the present study the values obtained were higher for female than for male newborns.
