  1. 1DWW = direct weaning weight; MWW = maternal weaning weight; SD = standard deviation; LHPD95, UHPD95 = lower and upper limits for the 95% HPD interval
  2. Heritabilities (diagonals) and correlations (off-diagonals) are expressed with reference to the F2 population. Summary measures of heritabilities were calculated using the weighted sum of additive variances by origin divided by the phenotypic variance at each cycle; correlation summaries were computed using the weighted sum of direct-maternal genetic covariance by origin divided by the product of additive standard deviations at each cycle
