Abstract
Genes do not directly produce criminal behavior, but they affect psychological traits which in turn affect the likelihood of lawbreaking. Intelligence and personality are the traits most strongly implicated in this chain. Since crime correlates with IQ and IQ is partly inherited, a heritable susceptibility to criminal behavior follows. Personality has a heritable component, although not to the same degree as IQ, and various aspects of personality have varying degrees of heritability. 12 references.
