Twin studies are commonly used in research on heredity and environment as they allow for the comparison of identical twins, who share 100% of their genes, and fraternal twins, who share only about 50% of their genes. By comparing the similarities of intelligence between these sets of twins, researchers can estimate the degree to which genetics and environment contribute to intelligence.
