Generations 7 to 14 of the second population were used in several combinations as training (PEn) and evaluation (PEv) subpopulations. Thereafter, 20 males and 200 females were used to generate a second 14-generation population, with 6,400 individuals per generation and its corresponding phenotype and genotype in SNP terms. A first population, effective population size 800 and 100 generations, was simulated using the QMSim program to generate linkage disequilibrium. The objectives of this study were to compare accuracies (R 2) of genomic values (GVs) and to estimate genetic correlation between true genetic values and genomic values obtained using predicted breeding values (EBV) and deregressed EBV (DEBV) as response variables. Highly accurate predicted genetic values must be obtained at an early age to promote rapid genetic progress.
