Univariate heritability estimates obtained from the AE model, given in Table 5, indicate moderately large heritable differences in all phenotypes, with estimates relatively similar for the two genders. Genetic correlations from the AE model are presented in Table 6. These were largely similar for males and females, and indicate substantial genetic overlap among the ERP measures (P3 and TF-PC1). Overlap between these and beta was much more modest, and was approximately twice as great among males as among females. Genetic correlations with EXT are modest but significant with one exception: the P3-EXT correlation in females was not significant.
