Path analysis is used to analyze family resemblance for eight principal components extracted from 30 anthropometric measurements of the craniofacial complex. Based on likelihood ratio tests, the null hypothesis of no assortative mating is rejected for the nasal height component. The null hypothesis of no common sibling environmental effect is rejected for the cranial size, craniofacial breadth, and nasal height components. Finally, the hypothesis that transmission from both mother and father is equal to 1/2, consistent with simple autosomal polygenic inheritance, is rejected for components corresponding to craniofacial breadth and upper facial height, thus implicating some effect of familial environment. Transmissibility is higher for components related to cranial size and facial height than for those related to facial breadth or ear dimensions.
路径分析用于分析从颅面复合体的30项人体测量中提取的8个主要成分的家族相似性。基于似然比检验，鼻高成分的无选型交配零假设被拒绝。颅大小、颅面宽度和鼻高成分的无共同同胞环境效应零假设被拒绝。最后，与简单常染色体多基因遗传一致的父母双方传递率均等于1/2的假设，对于颅面宽度和上面部高度相应成分被拒绝，从而暗示了家族环境的某种影响。与颅大小和面部高度相关的成分的传递率高于与面部宽度或耳部尺寸相关的成分。
