Sex and age are included as covariates in every model. Significance and comparative statistics for the reduced models (AE and CE) are obtained by comparison with the respective full ACE|ADE model. (All ACE|ADE models fit were considered good compared to the respective full saturated models). Reported χ2 df = 1 for the full vs. reduced model (e.g., AE vs. ACE) and df = 6 for all saturated vs. full model. * Final reduced models.
−2LL − 2 Log likelihood, AIC Akaike information criterion, df degrees of freedom, A additive genetic, C|D common environmental or dominance genetic, E unique environmental and error.
