From: Balanced selection on purebred and crossbred performance increases gain in crossbreds
Cumulative response to selection. 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 animals. OD =  % QTL with over-dominance. Inset plots show the mean performance of crossbred animals under each model for generations 30 to 40
