The results of the univariate model fitting for AAB are presented in Table 3. A full sex-limitation model allowing for sex-specific shared environmental influences was not fitted, as results from both the Full rA model as well as separate models of AAB for each sex (not shown) indicated no effect of shared environment for females and a small, non-significant effect of shared environment for males. The best-fitting model was the scalar model, which indicated that genetic and environmental influences accounted for proportionally the same amount of variance in AAB for males and females.
