The general lack of phenotypic correlation among skeletal nonmetric traits has been interpreted as indicating a lack of genetic correlation among these traits. Nonmetric traits scored on animals in the skeletal collection of rhesus macaques from Cayo Santiago are used to calculate phenotypic, genetic, and environmental correlations between traits. The results show that even when phenotypic correlations are low, there may be large, significant genetic correlations among these traits. The genetic correlation pattern suggests that genes which affect nonmetric trait variation act primarily at a local level in the cranium, even though there are genes with pleiotropic effects on skeletal nonmetric traits throughout the cranium. Environmental and phenotypic correlations do not show this neighborhood pattern of correlation.
骨骼非度量性状之间普遍缺乏表型相关性，这被解释为表明这些性状之间缺乏遗传相关性。对来自圣地亚哥岛的恒河猴骨骼标本中的动物进行评分的非度量性状，用于计算性状之间的表型、遗传和环境相关性。结果表明，即使表型相关性较低，这些性状之间可能存在很大的、显著的遗传相关性。遗传相关性模式表明，影响非度量性状变异的基因主要在颅骨的局部水平起作用，尽管在整个颅骨中存在对骨骼非度量性状具有多效性影响的基因。环境相关性和表型相关性并未显示出这种邻域相关性模式。
