If a trait has a high heritability, then adopted children are more likely to share the trait with
A) their biological parents.
B) their adoptive parents.
C) schoolmates.
D) other adopted children.
Answer: A
Rationale: If adopted children are more like their biological parents than their adoptive parents on measures of traits such as personality and intelligence, this tells us that there is a strong genetic component to these traits. On the other hand, if the children are more like their adoptive, genetically unrelated parents, a strong case can be made that environmental factors outweigh the biological predispositions.
