Accuracies of predicting genomic breeding values using GREML for different scenarios using multiple populations. Violin plot depicting the accuracies of genomic prediction using GREML and a (a) heritability of 0.95, or (b) heritability of 0.3 for five different scenarios. Base = reference population Holstein Friesian (HF), selection candidates HF; 1 = reference population HF, selection candidates Groninger White Headed (GWH); 2 = reference population HF and Meuse-Rhine-Yssel (MRY), selection candidates GWH; 3 = reference population HF, selection candidates MRY; 4 = reference population HF and GWH, selection candidates MRY
