Twins who are truly fully identical Brigette Paula Powers

Twins are often used in studies designed to uncover the effects of nature and nurture. Identical twins share the exact same genes, so some researchers hypothesize that differences between them must be due to the environment. By comparing the results between fraternal twins and identical twins, researchers can begin to determine the relative extent that nature or nurture played in any given outcome. The environment has a key role in shaping our epigenetic profiles, which in turn influence the activity of our
