Abstract
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 1316 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
