Of a total 885 marriages studied in the Mala population of the Chittoor district, 321 were consanguineous (36.37%), a figure higher than that reported previously by Sanghvi (1966) for the Harijans of Andhra Pradesh and Mukherjee (1974) for the Malas of Chandragiri taluk in the Chittoor district. The temporal trend of consanguineous marriages through the generations shows a decreasing trend towards the present generation. The inbreeding coefficient for autosomal loci is 0.0242, which is lower than that of the Harijans (0.029) in Sanghvi. The effects of inbreeding on fertility, mortality, and morbidity in this population are not consistent nor are they in agreement with the results of some studies reported earlier. In genetic load, the negative values of inbreeding load for total fetal loss, congenital malformations, and so on show the decreasing effect of inbreeding and sampling fluctuations.
