Translocation of Y chromosome to an autosome in the Bolivian owl monkey, Aotus.
Karyotypic study of a population sample of twenty-one owl monkeys, Aotus, originating from Bolivia, revealed two sex-specific somatic diploid chromosome numbers: 49 for  males and 50 for females. The presence of a trivalent in male meiotic figures and the identification of chromosomes by band pattern analysis confirmed the interpretation of a Y-autosome translocation in the males.
