A sex-limitation model was applied to the Multidimensional Personality Questionnaire (MPQ) data from the Minnesota Twin Family Registry. The sample included 626 monozygotic (MZ) twin pairs, 517 same-sex dizygotic (DZ) twin pairs, and 114 opposite-sex DZ twin pairs ranging in age from 27 to 64 years (mean age = 37.8). In addition, whenever possible, family members of the twins were also assessed: 1,690 spouses, 495 parents, 322 siblings, and 535 offspring. The goals of the present investigation were to analyze the covariance matrices to determine whether (a) there was evidence for sex limitation of heritability of the MPQ scales and (b) there was evidence for nonadditive genetic influences on these scales. Significant sex differences in heritability were found for 3 of the scales: Alienation, Control, and Absorption. In addition, evidence for dominance was found for all scales except Traditionalism and Absorption.
一种性别限制模型被应用于明尼苏达双胞胎家庭登记处的多维人格问卷（MPQ）数据。样本包括626对同卵（MZ）双胞胎、517对同性异卵（DZ）双胞胎以及114对异性DZ双胞胎，年龄范围在27岁至64岁之间（平均年龄 = 37.8岁）。此外，只要有可能，双胞胎的家庭成员也会接受评估：1690名配偶、495名父母、322名兄弟姐妹以及535名后代。本研究的目的是分析协方差矩阵，以确定（a）是否有证据表明MPQ量表的遗传力存在性别限制，以及（b）是否有证据表明这些量表存在非加性遗传影响。在其中3个量表上发现了显著的遗传力性别差异：疏离性、控制性和专注性。此外，除了传统主义和专注性量表外，在所有量表上都发现了显性的证据。
