Knowledge of dominance effects should improve ge­netic evaluations, provide the accurate selection of purebred animals, and enable better breeding strategies, including the exploitation of het­erosis in crossbreeds. In this study, we combined genomic and pedi­gree data to study the relative importance of additive and dominance genetic variation in growth and carcass traits in an F2 pig population. Two GBLUP models were used, a model without a polygenic effect (ADM) and a model with a polygenic effect (ADMP).
