Mean squared error of genomic estimated breeding values from algorithm for proven and young single-step GBLUP (APY ssGBLUP) with different core definitions and core sizes for average daily gain in nursery (ADGn), average daily gain in finishing (ADGf), and backfat (BF). Core sizes determined based on the number of largest eigenvalues explaining 50% (n = 160), 80% (n = 700), 90% (n = 1363), 95% (n = 2344), 99% (n = 7320) and > 99% (n = 10,000) of the genomic relationship matrix. The solid black line is the prediction accuracy estimated using regular ssGBLUP. All symbols are defined in Fig. 1
