Biometrical genetical techniques have been applied to the analysis of certain anthropometric characters measured in 134 pairs of adult twins. After allowing for assortative mating it appears that there is a family environment (E2) component for variation in height larger than previously reported. "Fatness" traits - weight, ponderal index, and skinfold thickness - all show higher heritabilities in males and substantial E2 components in females, and reasons for this are discussed. The same is true for cephalic index and forearm length but the reason for these differences is not so obvious. Head length shows a much higher heritability than head breadth. A larger sample of DZ opposite-sex pairs would allow more powerful discrimination, but the variety of patterns of variation revealed by the model-fitting approach used here justify its use over more traditional techniques.
生物统计学遗传技术已应用于对134对成年双胞胎所测量的某些人体测量特征的分析。在考虑到选型交配后，似乎身高变异存在一个比先前报道更大的家庭环境（E2）成分。“肥胖”特征——体重、体质指数和皮褶厚度——在男性中均显示出较高的遗传力，在女性中则有显著的E2成分，并对此进行了讨论。头指数和前臂长度也是如此，但这些差异的原因并不那么明显。头长的遗传力比头宽高得多。更大样本的异卵异性双胞胎对将允许进行更有力的区分，但此处使用的模型拟合方法所揭示的各种变异模式证明了其优于更传统技术的使用价值。
