Japanese macaques, Macaca fuscata, are seasonal breeders and live in groups
containing several female matrilines and unrelated males which are the dispersing
sex. Groups are structured according to a despotic dominance hierarchy and from
free living populations it is reported that most offspring is sired by high-ranking
males. We investigated the distribution of paternity in a large semi-captive group of
Japanese macaques (n= 140 individuals in 2010) containing an unusually high number
of sexually mature males to females (32:41). The group originates from a founder
population of 40 individuals imported to the Affenberg Landskron, Austria, in 1996.
No transfer of individuals occurred since then except for one male who was
integrated into the group in 2004.We collected hair samples from 104 mature and
immature individualsand extracted the DNA in 5%-Chelex-Solution containing also
Proteinase K. We used eight primers for genotyping ? five human primers (D5S820,
D6S493, D6S501, D12S67, D19S582) and three macaque specific primers (MFGT5,
MFGT24, MFGT25). Paternity could be dissolved in 45 individuals. Results show that
high ranking maleswere not more likely to father offspring than low ranking males
(?²=3.00, DF=2, p=0.223). With the exception of two individuals, parents were not
closely related, i.e. r
