Estimates of genetic correlations (above diagonal) of permanent environmental correlations (below diagonal), of heritability (bold on the diagonal), of repeatability (diagonal), and of the proportion of variance explained by markers (last row) for breaking strength measured at the equator (BSe) at 26 or 65 wk of hen age and at poles (BSp) at hen ages of 42 or 86 wk, and for dynamic stiffness (Kdyn) measured at all 4 hen ages.
