Heritability (ie, genetic influence) is indicated when the correlation coefficient for identical twins exceeds that for fraternal twins, indicating that shared dna is an important determinant of personality. Findings of genetic influences for child-based studies and little or no genetic influences for parent-based designs suggest that parents' negativity is not influenced by parental genotypes but is influenced by, and is a response to, children's genetically influenced characteristics.

To resolve the separate inﬂuence of genetic and shared environmental factors on the familial resemblance that characterizes the vast majority of behavioral traits: twin studies, adoption studies, and gene identiﬁcation methods.

Mental influences or inflate the estimates of nonadditive genetic influences we can conceive of several processes that would result in a distor- tion of self-reports provided by twins reared together. The best reason to be cautious about attributing all the personality similarities of separated twins to genetic factors is that a home environments have less impact on personality than does peer influence.
