title: Inbreeding effect on precocious mortality in Japanese communities of Brazil.
abstract: 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.
