  1. Accuracy was measured as correlation between true BV and EBV.
  2. aS12L2 × 3, group size = 12, a litter into two groups.
  3. bAll: all animals; Group I: the animals which were genotyped in the 30% genotyping scenario; Group II: the animals which were not genotyped in the 30% genotyping scenario.
  4. cValid_R, validation for animals with records; Valid_nR, validation for animals without records.
  5. dG/I ratio, ratio of accuracy for EBV predicted using group records to accuracy of EBV predicted using individual records.
  6. eS12Lran, group size = 12, individuals random assigned to groups.
  7. fS24L2 × 3, group size = 24, a litter into two groups.
