对堕胎和同性恋权利态度的生物学和社会传递在成年双胞胎、兄弟姐妹和他们的父母中进行了大样本分析。我们提出了一个关于家庭相似性的线性模型，允许从父母到后代的态度的遗传和文化传递，以及表型分类交配(结婚相似的倾向)和其他不依赖于父母态度的双胞胎和兄弟姐妹相似的环境来源。该模型与这两个项目亲属之间的相似模式非常吻合。这一结果与遗传易感性在这两种态度传递中的重要作用是一致的。与社会和政治科学的主导范式相反，亲属关系数据与父母态度对子女成人态度发展的相对较小的非遗传影响是一致的。相比之下，择偶是一种社会行为，对社会态度的两极分化和父母对下一代施加的长期影响有显著影响。
The biological and social transmission of attitudes toward abortion and gay rights are analyzed in a large sample of adult twins, siblings, and their parents. We present a linear model for family resemblance allowing for both genetic and cultural transmission of attitudes from parents to offspring, as well as phenotypic assortative mating (the tendency to marry like) and other environmental sources of twin and sibling resemblance that do not depend on the attitudes of their parents. The model gives a close fit to the patterns of similarity between relatives for the two items. Results are consistent with a substantial role of genetic liability in the transmission of both attitudes. Contrary to the dominant paradigm of the social and political sciences, the kinship data are consistent with a relatively minor non-genetic impact of parental attitudes on the development of adult attitudes in their children. By contrast, the choice of mate is a social action that has a marked impact on the polarization of social attitudes and on the long-term influence that parents exert upon the next generation.
