r, phenotypic correlation (Pearson’s correlation coefficient); rA, genetic correlation; rC, shared environmental correlation; rE, unique environmental correlation; Bivariate A, proportion of the phenotypic correlation between 2.5 and 9 years explained by common additive genetic influences; Bivariate C, proportion of the phenotypic correlation between 2.5 and 9 years explained by common influences from the shared environment; Bivariate E, proportion of the phenotypic correlation between 2.5 and 9 years explained by common influences from the unique environment.
