行为遗传学领域已经证明， 影响着人们行为的许多方面， 包括认知能力人格和精神病理学 然而，人们对遗传因素在多大程度上 影响成对行为交互的因素 个体 从儿童发展的角度来看， 最重要的互动是家庭内部的互动， 从本质上讲，对这种家庭关系一无所知， 行为遗传学的观点。 这项研究将延伸到青春期早期，科罗拉多 兄弟姐妹研究（CSS），重点是社会环境， 家庭和家庭外的关系。 CSS有 以前研究过的非收养和 收养的兄弟姐妹在早期和中期儿童。 本研究 将研究非共享环境， 遗传对父母和兄弟姐妹关系的影响。 本研究纳入长期科罗拉多收养 项目，这使得研究先例和 家庭关系的后果，并考虑家庭关系的作用， 在这些协会的遗传。

The field of behavioral genetics has demonstrated that heredity influences differences among people for many aspects of behavior, including cognitive abilities, personality, and psychopathology. However, little is known about the extent to which genetic factors influence behavioral interactions for pairs of individuals. From the perspective of child development, some of the most important interactions are those within the family, yet essentially nothing is known about such family relationships from the perspective of behavioral genetics. This research will extend into early adolescence the Colorado Sibling Study (CSS) which focuses on the social environment of familial and extra-familial relationships. The CSS has previously studied family relationships for nonadoptive and adoptive siblings in early and middle childhood. This research on early adolescence will investigate nonshared environment and genetic influence on parent and sibling relationships. This study is embedded within the long-term Colorado Adoption Project, which makes it possible to study antecedents and consequences of family relationships and to consider the role of heredity in these associations.
