Adoption studies are an important tool of behavioural genetics because they:
A) allow us to examine the effects of nonrelated mothering
B) allow us to look at the contributions of environment and genetics on behaviour
C) are so rare
D) show that environment overwhelms the effect of genes

Question

Quizplus · Accepted Answer

Adoption studies allow researchers to separate the effects of genetics and environment on behaviour because adopted children typically do not share genes with their adoptive parents. By comparing adopted children to their biological and adoptive families, researchers can gain insight into how much of a child's behaviour is influenced by genetics and how much is influenced by their environment.
