确定了生活在圣地亚哥岛的 293 只自由放养的猕猴的 8 个多态性基因座的红细胞表型；这个数字代表了岛上的总人口，分为四个社会群体加上外围男性。恒河猴种群在血型系统（位点）和社会群体方面表现出显着的遗传异质性。没有特定的遗传位点或社会群体对观察到的遗传异质性负有唯一的责任。两个基因座（G 和 H）的基因型分布在社会群体或整个人口中并没有显着偏离 Hardy-Weinberg 预期。对人口细分影响的均衡预期的修正没有产生统计上显着的结果。总体而言，结果表明，多种过程（随机遗传漂变、创始人效应、迁移和选择）的相互作用可能是造成观察到的多样性的原因。这些数据与进一步研究的数据相结合，可能允许将行为和遗传知识应用于非人类灵长类动物微进化过程的研究。
The red blood cell phenotypes for eight polymorphic loci were determined for 293 free-ranging Macaca mulatta living on Cayo Santiago; this number represents the total population of the island, disposed in four social groups plus peripheral males. The rhesus population shows significant genetic heterogeneity over blood group systems (loci) and social groups. No particular genetic locus or social group is solely responsible for the genetic heterogeneity observed. The distributions of genotypes for two loci (G and H) do not deviate significantly from Hardy-Weinberg expectations within social groups or in the population as a whole. Correction of the equilibrium expectations for the effect of population subdivision yields no statistically significant results. Overall, the results suggest that the interaction of a variety of processes (random genetic drift, founder effect, migration and selection) may be responsible for the diversity observed. These data, combined with those from further studies, may allow an application of behavioral and genetic knowledge to the study of microevolutionary processes among nonhuman primates.
