金卡茹社会群体通常由一个成年雌性、两个雄性、一个亚成体和一个少年组成。基于11个微卫星位点的变异分析，我们评估了四个社会群体内和之间的亲属关系，共25个kinkajous。我们使用排除和似然分析为8个样本中的7个指定父母，5个具有≥ 95%的确定性，2个具有≥ 80%的确定性。六分之五的群体后代的父亲来自同一个社会群体的母亲和小狗。成年男性和女性在一组是无关的，亚成体和青少年的后代组成人，这表明一个家庭的结构。在一个社会群体中，所有五个被确定的父系都是由该群体中占主导地位的男性确定的。然而，这种交配的不对称性并不一定反映合作，由于一组内的两个成年男性之间的亲属关系，作为两个成年男性对采样是无关的。相邻的男性kinkajous更密切相关的彼此比相邻的女性kinkajous，这表明女性分散更频繁或更远的男性。
Kinkajou social groups generally consist of one adult female, two males, one subadult and one juvenile. Based on analysis of variation in 11 microsatellite loci, we assess the degree of kinship within and between four social groups totaling 25 kinkajous. We use exclusion and likelihood analyses to assign parents for seven of the eight offspring sampled, five with ≥ 95% certainty, and two with ≥ 80% certainty. Five of six identified sires of group offspring came from the same social group as the mother and pup. Adult males and females within a group were unrelated and subadults and juveniles were offspring of the group adults, suggesting a family structure. All five identified paternities within a social group were by the dominant male of the group. However, this copulation asymmetry does not necessarily reflect cooperation due to kinship ties between the two adult males within a group as one of two adult male pairs sampled was unrelated. Neighbouring male kinkajous were more closely related to each other than neighbouring female kinkajous, suggesting that females disperse more often or farther than males.
