黑猩猩雄性交配策略的相对成功，雄性优势地位的作用和近亲繁殖避免行为的成功，只能在父系是已知的评估。我们报告的可能paternities的14只黑猩猩包括在长期的黑猩猩（Pan troglodytes schweinfurthii）在贡贝国家公园，坦桑尼亚的行为研究。从脱落的毛发和粪便中非侵入性地收集DNA样品，并使用人类特有的13-16个微卫星位点进行基因分型。所有14个后代都可以分配给社区内的父亲。虽然有一个男性等级和生殖成功之间的正相关关系，我们证明了一系列的男性交配策略（占有欲，机会主义交配和财团）可以导致所有男性等级的父权。几只成年雌性面临与近亲雄性繁殖的风险。大多数成功地避免了近亲繁殖，但在一个案例中，一个高级别的男性在社区与他的母亲交配，并产生了后代。与最近关于黑猩猩的数据相反（P。verus），在我们的研究中没有观察到组外父系的证据。重新分析泰数据使用可能性的方法提出了怀疑的发生在该社区的额外组的父权。
The relative success of chimpanzee male mating strategies, the role of male dominance rank and the success of inbreeding avoidance behaviour can only be assessed when paternities are known. We report the probable paternities of 14 chimpanzees included in a long-term behavioural study of chimpanzees (Pan troglodytes schweinfurthii) at Gombe National Park, Tanzania. DNA samples were collected noninvasively from shed hair and faeces and genotyped using 13-16 microsatellite loci characterized in humans. All 14 offspring could be assigned to fathers within the community. While there is a positive relationship between male rank and reproductive success, we demonstrate that a range of male mating strategies (possessiveness, opportunistic mating and consortships) can lead to paternity across all male ranks. Several adult females were at risk of breeding with close male relatives. Most successfully avoided close inbreeding but in one case a high-ranking male in the community mated with his mother and produced an offspring. In contrast to recent data on chimpanzees (P. t. verus) from the Tai forest, Cote d'Ivoire, no evidence of extra-group paternity was observed in our study. Reanalysis of Tai data using a likelihood approach casts doubt on the occurrence of extra-group paternity in that community as well.
