Chunk #64 — II. G × E Interaction in Aggressive Behavior — A. Potential moderators of genetic influence found in adoption and twin studies — 1. Family adversity and social disadvantage
These studies using the moderated variance components approach (e.g., Button et al., 2005; Rowe et al., 1999; Tuvblad et al., 2006), all examine whether an environmental (risk) factor moderates genetic and environmental variance on antisocial and aggressive behavior. Findings from these studies show that heritable influences on aggressive behavior vary depending on environmental context, indicating the importance of the environmental risk factors in the development of aggressive behavior as well as for gene expression.
