Abstract
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.
摘要
对来自玻利维亚的21只夜猴（夜猴属）群体样本进行的核型研究表明，存在两种特定性别的体细胞二倍体染色体数：雄性为49条，雌性为50条。在雄性减数分裂图像中出现的三价体以及通过带型分析对染色体的鉴定，证实了雄性中存在Y-常染色体易位的解释。
