分析Loehlin和Nichols（1976）经典双胞胎研究的数据，我们计算了男性工具性(M)、女性表达性(F)和性别诊断性（GD）的测量值。性别内M、F和GD个体差异的定量遗传建模分析表明：(1)加性遗传因素对M、F和GD的个体差异有显著影响。(2)环境对M、F和GD的影响趋于非共享。(3) M、F和GD个体差异的遗传和环境因素倾向于不呈现性别差异。最后，(4)GD的估计性别内遗传力（0.53）显著大于M的估计性别内遗传力（0.36）或F的估计性别内遗传力（0.38）。
Analyzing data from Loehlin and Nichols's (1976) classic twin study, we computed measures of Masculine Instrumentality (M), Feminine Expressiveness (F), and Gender Diagnosticity (GD). Quantitative genetic modeling analyses of within-sex individual differences in M, F, and GD indicated that: (1) Additive genetic factors contribute significantly to individual differences in M, F, and GD. (2) The environmental effects on M, F, and GD tend to be nonshared. (3) The genetic and environmental components of individual differences in M, F, and GD tend not to show gender differences. Finally, (4) the estimated within-sex heritability of GD (.53) is significantly greater than the estimated within-sex heritabilities of either M (.36) or F (.38).
