^aConsidering only the top 10 LD blocks explaining most of the genetic variance for purebred or crossbred performance
gVar PB = percentage of genetic variance explained by a LD block for purebred performance
gVar CB = percentage of genetic variance explained by a LD block for crossbred performance
BF = back fat thickness, ADG = average daily gain, and RFI = residual feed intake
S_PB = PB performance for S breed, LR_PB = PB performance for LR breed, and LW_PB = PB performance for LW breed
S_CB = CB performance for S breed-of-origin, LR_CB = CB performance for LR breed-of-origin, and LW_CB = CB performance for LW breed-of-origin
