We investigated the relatedness among adult females in wild Rhesus macaque (Macaca Mulatta) to understand what kinship affects social behavior. DNA were extracted from fecal samples and microsatellite markers were used for establishing kinship network. Totally 117 specimens of 38 individuals were used to perform molecular experiment, each individual was collected more than 2 specimens, each specimen was amplified over than 3 times. 6 high polymorphic microsatellite loci of 10 candidate loci were selected successfully. On average, the PIC value (Polymorphism information content) of microsatellite loci was 0.567, ranging from 0.467 to 0.744. Establishing kinship network and comparing it with affiliative behavior network, we found that significant correlation between kinship network and affiliative behavior network, which supported to kin selection theory. Supporting by hierarchy data, genetic similarity is useful to determine the pedigrees and to explain social behavior.
