Quizplus · Accepted Answer

Twin studies are commonly used in behavior genetics to examine the influence of heredity on behavior. This is because identical twins share 100% of their genes, while fraternal twins share only about 50%. By comparing the similarities and differences in behavior between these twin pairs, researchers can estimate the heritability of certain traits or behaviors. As such, twin studies have been used to investigate the heritability of a wide range of traits such as intelligence, personality, and mental illness.
