Twin studies are typically used in the area of psychology to determine the relative contributions of genetic and environmental factors to intelligence and other characteristics. By comparing identical twins (who share 100% of their genes) to fraternal twins (who share only 50% of their genes on average), researchers can estimate the degree to which genetic factors contribute to individual differences in traits like intelligence, personality, and behavior.
