Consanguinity, fecundity and post-natal mortality in Karnataka, South India

The degree of consanguinity of the progeny, the number of live-borns and number of living children were determined in 3350 marriages in Bangalore, Karnataka. The coefficient of inbreeding (F) was 0-02308, higher than in comparable, urban populations in other South Indian states. No significant differences were found between the consanguineous and nonconsanguineous groups in numbers of live-born or living children nor was there any consanguinity-related trend with respect to these parameters.
