Resumo

The effects of inbreeding on reproductive outcome in terms of fertility and mortality were analyzed in seven tribal populations from Andhra Pradesh, India. The effect on mortality at both prenatal and prereproductive postnatal stages was further verified after estimating genetic load by an exponential regression model. Relatively higher fertility and mortality rates were recorded among consanguineous marriages than nonconsanguineous unions in the majority of tribes. The regression analysis indicated a positive, nonsignificant association between inbreeding and mortality in five tribes. Low B/A ratios were found in five tribes. © 1995 Wiley‐Liss, Inc.
