下颌骨的形状。用多变量技术研究了C57 BL/Gr的9个亚系、7个“C57祖先”的其它菌株和4个无关菌株。广义距离函数用于将个体分类到它们最相似的组中。错误分类的程度取决于菌株和亚系之间的系谱关系。子线质心对之间的广义距离也与它们之间的世代数高度相关（r = 0.60）。一个典型的变量分析被用来减少维数，使图形显示之间的关系菌株和亚系可以。结果与分类分析结果基本一致。得出的结论是，下颌骨的形状可以用于亚线识别，虽然这种技术的准确性取决于如何密切的亚线相关。
The shape of the mandible in. nine sublines of C57BL/Gr, seven other strains of ‘C57 ancestry’ and four unrelated strains was studied by multivariate techniques. The generalized distance function was used to classify individuals in the groups which they most closely resembled. The degree of misclassification depended on the pedigree relationship between strains and sublines. The generalized distance between pairs of subline centeroids was also highly correlated (r = 0·60) with the number of generations between them. A canonical variate analysis was used to reduce the dimensionality so that a graphical display of the relationships between strains and sublines could be made. The results agreed closely with the classification analysis. It was concluded that the shape of the mandible could be used for subline identification though the accuracy of this technique depends on how closely the sublines are related.
