环境或基因的影响，或两者兼而有之，都可以解释离异父母的后代离婚风险增加的原因。以前的研究使用协变量来统计控制混杂，但目前的研究是第一个关于该主题的遗传信息研究。这项调查使用了双胞胎的孩子设计，其中包括来自澳大利亚双胞胎登记处的双胞胎、他们的配偶和他们年轻的成年后代（n = 2310），以测试基于遗传或共同环境因素的选择是否占代际联系的一部分。分析还控制了父母双方的测量特征。结果表明，环境介导和遗传风险都解释了代际传递，支持选择和因果关系的作用。
Environmental or genetic influences, or both could account for the increased risk of divorce among the offspring of separated parents. Previous studies have used covariates to statistically control for confounds, but the present research is the first genetically informed study of the topic. The investigation used the Children of Twins Design with twins, their spouses, and their young adult offspring (n = 2,310) from the Australian Twin Registry to test whether selection on the basis of genetic or shared environment factors accounted for part of the intergenerational association. The analyses also controlled for measured characteristics of both parents. The results suggest that both environmentally mediated and genetic risk account for the intergenerational transmission, supporting the roles of both selection and causation.
