Document Summary

Iden&cal twins treated the same therefore they act the same. We can get around the same when comparing iden&cal twins reared together and part. Could be varia&on in traits due to di erent experiences: eats dinner at di erent &mes fall asleep at di erent &mes. Unique experiences playing role in behavior rather than genes or environment. Constantly upda&ng based o of past experiences. Tend to see high heritability es&mate for these two. Look at these family / iden&cal twin studies we regularly see iden&cal twins have higher concordance in traits than fraternal twins. Lifle less concordance when iden&cal twins reared apart than reared together which suggest environment must play some role. Higher iq in higher socio economic environments. Look at how much e ect environment may have on our traits. One way to look is reac&on range. Idea that for any given trait, there is a range of this traits expression.
