Adoptee studies compare genetic influences on behavior by examining adopted children in relation to their adoptive and biological parents.
Adoptee studies are a type of kinship study used to examine genetic influences on behavior. These studies compare adopted children to both their adoptive and biological parents to determine the impact of genetics on behavior.
In adoption studies, evidence for genetic influence is found when adopted children show traits more similar to their biological parents than their adoptive parents. Conversely, evidence for environmental influence is found when adoptees resemble their adoptive parents more than their biological parents.
Genotype-Environment Interactions in adoption studies reveal how genetic susceptibility interacts with the environment to influence behavior. These studies provide insights into how environmental effects differ based on genotype, especially in stressful environments for genetically at-risk children.
