[Chromosomal rearrangements and sterility in the lemur].

Autosomal rearrangements are one of the causes of human sterility, particularly in males, where they result in a considerable diminution of gametogenesis. The relationships between multivalents and trivalents, and problems of gametogenesis observed in certain lemur hybrids, make these animals a good model for the study of human male sterility of chromosomal origin.
