Genetic models are described which exploit the unique relationships that exist within the families of identical twins to obtain weighted least squares estimates of additive, dominance and epistatic components of genetic variance as well as estimates of the contributions of X-linked genes, maternal effects and three sources of environmental variation. Since all of the relationships required to achieve a resolution of these variance components are contained within each family unit, the model would appear to be superior to previous approaches to the analysis of quantitative traits in man.
文中描述了一些遗传模型,这些模型利用同卵双胞胎家族中存在的独特关系,来获得遗传方差的加性、显性和上位性成分的加权最小二乘估计,以及X连锁基因的贡献、母体效应和三种环境变异来源的估计。由于实现这些方差成分分解所需的所有关系都包含在每个家族单元中,该模型似乎优于以往对人类数量性状进行分析的方法。
