  1. For both models, the validation criterion was crossbred performance
  2. MA additive model, MAD dominance model, GEBV genomic estimated breeding value for purebred performance, GEBV-C genomic estimated breeding value for crossbred performance
  3. aPurebred: training in pure lines was done separately
  4. bCombined: genotyped sows from both pure lines were combined together to create a single training population
