Birth weight and survival in relation to natural selection.
Birth weight and perinatal mortality of 11,241 single born infants in Visakhapatnam (Andhra Pradesh, South India) are studied by fitting multiple regression techniques, with the natural log of the ratio of survivors to non-survivors. The optimal birth weight values are almost 475 g above the corresponding means. Selection intensity and selective mortality are relatively high.
