Twin and adoption studies are commonly used to distinguish between the effects of heredity (genes) and environment (upbringing and nurturing). These studies allow researchers to compare the similarities and differences between individuals who share different amounts of genetic material and have had different environmental experiences. By comparing the outcomes of identical twins who were raised together versus those who were separated at birth and raised in different environments, for example, researchers can attempt to isolate the effects of heredity and environment on traits or outcomes of interest. Therefore, twin and adoption studies have been most helpful for teasing apart the influences of heredity and environment.
