Both comparing monozygotic twins to dizygotic twins and comparing adopted children to their adoptive and birth families can help researchers discover if a personality characteristic is inherited. Monozygotic twins share 100% of their genes, whereas dizygotic twins share only 50% of their genes, so if a personality trait is more similar in monozygotic twins than dizygotic twins, it is likely that genetics plays a role. Similarly, comparing adopted children to their adoptive and birth families can help assess the relative contributions of genetics and environment to personality traits.
