Document Summary
Behavior genetics: the study of the relative power and limits of genetic and environmental influences on behavior. Heritability: the proportion of variation among individuals that we can attribute to genes. The heritability of a trait may vary, depending on the range of populations and environments studied. Norm: an understood rule for accepted and expected behavior. Individualism: giving priority to one"s own goals over group goals and defining one"s identity in terms of personal attributes rather than group identifications. Collectivism: giving priority to goals of one"s group (often one"s extended family or work group) and defining one"s identity accordingly: twin and adoption studies. Although identical twins have the same genes, they don"t always have the same number of copies of those genes. Therefore one may be more at risk for certain illness. On both extraversion (outgoingness) and neuroticism (emotional instability), identical twins are much more similar than fraternal twins.
