Abstract Paternity of 16 pigtail macaque offspring was determined using a DNA profile analysis and was based on two independent assays of the genome of each individual using multilocus DNA probes. The offspring were members of a group of 59 pigtail macaques, including 5 adult males, 1 subadult male, and 37 adult and subadult females. Rank was unrelated to paternity as the first ranking male sired 0, the second ranking male sired 3; the third ranking male sired 0, the fourth ranking male sired 8, and the fifth ranking male sired 2 offspring. The subadult male sired 0 offspring. The DNA analysis was effective in excluding possible sires of 3 offspring whose mothers had become pregnant by another male before being introduced to the study males. Subsequent semen evaluation revealed an absence of sperm in the semen of the alpha male, but revealed a sperm count within normal limits in the third ranking male, who also sired no offspring. Behavioral data focusing on male-offspring interactions found that offspring did not preferentially affiliate with their sire and that males did not affiliate with their offspring frequently enough for analysis. Thus, this study of one captive pigtail macaque group demonstrates that: (1) rank was not a predictor of reproductive success; and (2) there was no preferential attraction for one's own offspring by males or one's own sire by offspring.
