Table 3 Longitudinal analyses: heritabilities (h²), correlations (ρ_G, ρ_E, ρ_P), and proportion of additive genetic variance due to the effects of shared genes (ρ_G²) between the same traits between age-classes from bivariate quantitative genetic analyses of data from subjects measured in both the 4^th and 6^th decades of life.
