Table 3 Longitudinal analyses: heritabilities (h2), correlations (ρG, ρE, ρP), and proportion of additive genetic variance due to the effects of shared genes (ρG2) between the same traits between age-classes from bivariate quantitative genetic analyses of data from subjects measured in both the 4th and 6th decades of life.
