Gender, genetic risk, and criminal behavior.

The threshold hypothesis asserts that the prevalence of offending is lower among females because females have a higher threshold for risk than males. As a result, females who do offend should exhibit greater concentrations of genetic and environmental risk than male offenders. In light of these statements, the current study examines the role of genetic factors in the etiology of female offending using data from the National Longitudinal Study of Adolescent Health. The results reveal that the genetic risk threshold is higher for females than for males. However, contrary to the threshold hypothesis, female offenders exhibit fewer genetic risks than male offenders.
