From: Balanced selection on purebred and crossbred performance increases gain in crossbreds
Mean phenotypic average of pure breeds. Mean phenotype of pure breeds are expressed relative to the means obtained with the reference selection criterion (w = 0). The general criterion for selection of purebred parents was \(SC_{i} = \left( {1 - w} \right) \cdot {\text{GEBV}}_{iP} + w \cdot {\text{GEBV}}_{iC}\). Training under genetic Models 2 and 3 was on purebred data. OD = % QTL with over-dominance
