Numbers of individuals for Landrace (LR), three-way crossbred (CB), and extra three-way crossbred pigs (CB-extra) in the training and validation sets per trait, i.e. average daily gain (ADG), back fat thickness (BF), and loin depth (LD)
* Three-way crossbred pigs with only phenotypic information, no genotyped
