  1. 1gEBV = genomic estimated breeding value; 2ptEBV = progeny test estimated breeding value; 3number of phenotypes available, as not all individuals that were genotyped were phenotyped for all traits; 4the traits were growth and composition traits of pigs; 5SC1 = only the phenotypes of the 3 025 genotyped animals that were not part of the validation population were used to train the prediction equation; 6SC2 = the phenotypes of the 3 025 genotyped animals that were not part of the validation population and the phenotypes of the 2 939 other animals in the pedigree that were not genotyped were used to train the prediction equation; 7SSAI = single stage methodology of AlphaImpute; 8SSMi = single stage methodology of Misztal et al. [9].
