The homogeneity model results for neglect suggest that about one quarter of the variance is due to genetically driven child effects and the shared and twin environments each exert a small effect. The remaining two-thirds of the variance are due to nonshared environmental factors and error. The heterogeneity model results suggest that there are moderate genetic influences on neglect for females, but very little for males. The shared and twin environments combined explain 28% of the variance in males’ experience of neglect.
