Effect of reference population size on the annual genetic gain (AGG) of the meat breeding program. (a) Gains on meat trait and (b) gains on maternal trait. Different lines indicate different scenarios at the optimized variables: GS = pure genomic selection, GS-pheno = combined genomic and a meat phenotype selection, GS-PT-index = genomic selection and progeny testing, and Class-PT-culling = conventional selection. For genomic scenarios, the genomic prediction accuracy (rGBV) was calculated considering Ne = 200 and a genome size of 27 Morgan.
