在824名男性双胞胎及其父母的样本中，研究了遗传和环境对自我报告的亲子关系的影响。在11岁和17岁的双胞胎相似性的横截面比较，以确定遗传和环境因素对家庭关系的贡献的发展变化。显着的遗传影响被发现对亲子冲突的看法，考虑，参与和整体支持。年龄较大的双胞胎的遗传率明显较高，这表明随着年龄的增长，遗传影响力增加。年龄差异主要表现在父子关系上。这些结果支持了S. Scarr和K. McCartney（1983）指出，活跃的基因-环境相关性在青春期增加。年龄较大的青少年可能有更多的选择和影响的性质，他们与父母的关系。
Genetic and environmental influences on self-reported parent-child relationships were examined in a sample of 824 individual male twins and their parents. Cross-sectional comparisons of twin similarity at ages 11 and 17 were undertaken to identify developmental changes in the contribution of genetic and environmental factors to family relationships. Significant genetic influences were found on perceptions of parent-son conflict, regard, involvement, and overall support. Heritabilities were significantly higher in older twins, suggesting increased genetic influence with age. Age differences were present primarily in the father-son relationship. These results provide support for the proposal of S. Scarr and K. McCartney (1983) that the importance of active gene-environment correlations increases during adolescence. Older adolescents may have more choice and impact on the nature of the relationships they have with their parents.
