  1. Pearson’s correlations (r) and mean squared errors (MSE) between the reliabilities of GEBV, the intercept (b0) and slope (b1) from the regression of the exact reliabilities on the approximate reliabilities of GEBV for the non-genotyped animals based on Data 1 (milk yield) and lactation 3
  2. aExact reliabilities of GEBV computed by inverting the coefficient matrix of the mixed model equations
