Quizplus · Accepted Answer

Heritability can account for about half of an individual's intelligence. Determining the role of heritability in the intelligence of family members is challenging, as they often live together and are exposed to similar environments. The best way to study genetic influence is to study twins and siblings who were adopted by and raised in separate families. Adoption studies have found a high correlation between the intelligence of twins and siblings.
