A general description of the simulation and workflow: a) A 30-chromosome genome was simulated with 200 QTL randomly distributed across 2 chromosomes and the remaining 28 chromosomes harboring no QTL. b A schematic representation of the pedigree simulation (7 generations of 3.5 k individual each). The first six generations (21 k phenotyped individuals and half of them genotyped) were used for training. The last generation consisting of 3.5 k genotyped and non-phenotyped individuals was used as validation set. Preselection of SNPs was based either on the absolute estimated marker effects or FST scores calculated using data from the training population
