Inbreeding effect on precocious mortality in Japanese communities of Brazil.
Data on precocious mortality (from abortions up to the age of 20) are presented for three Japanese communities in Brazil. The inbreeding load (B approximately 1-5) is estimated on the basis of these data. B/A lies between 7 and 30. Three general working hypotheses are presented.
