Abstract
Five genetic markers were employed to attempt to identify the fathers of 135 Macaca mulatta offspring living in large outdoor field cages. Family studies of two of these markers to confirm mode of inheritance of phenotypes had not heretofore been reported. Of the 284 exclusions required to identify the fathers of all 135 monkeys, 198 (or 70 percent) were possible using only these five genetic polymorphisms. For 58 (or 43 percent) of these 135 offspring the father was identified. These data were applied to estimate the association between dominance rank of fathers and reproductive success. Fertility of first‐ and second‐ranking fathers was judged to be about twice as high as that of third‐ and fourth‐ranking fathers.
