Rhesus macaque females regularly copulate with a number of partners, and produce a single offspring per reproductive cycle in over 99% of cases. We used genotyping of 10 STR markers to determine paternity in the Cayo Santiago population of rhesus macaques. About 1,500 monkeys have been analyzed to date, with their marker genotypes entered into a computerized database. These data enable us to report the first documented case in any cercopithecine nonhuman primate species of the production of twin offspring sired by different males.
恒河猴雌性会定期与多个伴侣交配，并且在超过99%的情况下每个生殖周期只产下一胎。我们使用10个短串联重复序列（STR）标记进行基因分型，以确定圣地亚哥岛恒河猴种群中的父系情况。迄今为止，已经分析了约1500只猴子，并将它们的标记基因型录入了计算机数据库。这些数据使我们能够报告在任何猕猴科非人灵长类物种中首次有记录的由不同雄性孕育双胞胎后代的案例。
