Sib correlations for height and weight decrease with absolute age difference. Parent-child correlations increase with age of child, with greater resemblance to the mother than the father. Estimates of the relative variance due to common environment are greater, and heritability estimates less, than for earlier studies. Heritability is less for adults than children. There is no significant major locus for height or weight.
身高和体重的同胞相关性随绝对年龄差而降低。亲子相关性随孩子年龄增加,与母亲的相似性高于父亲。与早期研究相比,共同环境导致的相对方差估计值更大,遗传力估计值更小。成年人的遗传力低于儿童。身高或体重不存在显著的主基因座。
