从社会结构和差异交配成功的遗传结构的可预测性进行了测试，在野生狒狒。狒狒种群被细分为有凝聚力的社会群体，包括多个成年人的性别。在许多哺乳动物中，雄性是分散的性别。社会结构和行为成功地预测了生殖成功的相关性和方差的分子遗传措施。在野生灵长类动物中的优先访问模型的第一次定量测试中，通过分子遗传分析证实了显性雄性的生殖优先权。然而，由此产生的高短期变异生殖成功并没有转化为同样高的长期方差，因为男性的优势地位是不稳定的。高但不稳定的短期方差的一个重要后果是，年龄组将倾向于父亲的兄弟姐妹和社会群体将遗传亚结构的年龄。
The predictability of genetic structure from social structure and differential mating success was tested in wild baboons. Baboon populations are subdivided into cohesive social groups that include multiple adults of both sexes. As in many mammals, males are the dispersing sex. Social structure and behavior successfully predicted molecular genetic measures of relatedness and variance in reproductive success. In the first quantitative test of the priority-of-access model among wild primates, the reproductive priority of dominant males was confirmed by molecular genetic analysis. However, the resultant high short-term variance in reproductive success did not translate into equally high long-term variance because male dominance status was unstable. An important consequence of high but unstable short-term variance is that age cohorts will tend to be paternal sibships and social groups will be genetically substructured by age.
