of no G × E correlation is violated, heritability estimates for aggressive behavior in twin studies could include both additive genetic effects and the effects of G × E correlation (i.e., heritability estimates are inflated). Apart from these specific examples cited here, few studies have examined the effects of rGE in aggressive behavior, making it difficult to know the extent of their effect on heritability estimates in twin studies.
