Quizplus · Accepted Answer

Behavior geneticists use twin studies to estimate trait heritability by comparing the similarities in traits between identical (monozygotic) twins who share 100% of their genes and fraternal (dizygotic) twins who share only 50% of their genes. By examining the differences in heritability between these two groups, behavior geneticists can estimate the degree to which a trait is influenced by genetics.
