AI-generated Abstract

This chapter investigates the genetic and environmental influences on aggression through a review of twin and adoption studies. It aims to quantify these influences and compare their patterns and magnitudes with those observed in broader antisocial behavior studies. Key findings indicate substantial genetic contributions to aggression, as well as the complexity of familial environmental factors. The review underscores the importance of differentiating between genetic and environmental factors in understanding the etiology of aggression and supports the growing molecular genetic research identifying candidate genes associated with aggressive behavior.
