  1. Situation normal: heritability equal to 0.5, size of the training population equal to 500 individuals, and all markers included in the data. Situation h2 = 0.25: heritability was decreased from 0.50 to 0.25. Situation nTr = 1,000: size of training population was increased from 500 to 1,000 individuals. Situation MAF > 0.10: markers with a MAF below 0.10 were excluded from the data. The table summarizes ten simulations for the scenario of intermediate number of QTL and equal QTL variance.
