Summary properties the P matrices of each cross type. ac Ellipsoid representations of the posterior modes of each matrix projected onto a subspace defined by the first three eigenvectors of P from the PL × PL cross. The axes explain 80%, 69% and 77% of the variance of P in the PL × PL, the SB × SB and the hybrid crosses, respectively. df Posterior densities, posterior modes and 95% CrIs of the three summary estimates of the matrices of phenotypic variance of each cross type, being d the overall phenotypic variance (Vtot), e the eccentricity (Ω), and f the angle (θ) between the first eigenvectors. Densities of the angle estimates between P of a cross type (from top to bottom: PL × PL, PL × PL, SB × SB) and a random matrix are shown in light grey. Cross type: SB = SB × SB offspring, PL = PL × PL offspring, F1 = hybrids. g Posterior modes and 95% CrIs of H for the observed data (dark blue) and the randomized P matrices (light grey)
