Numbers in italics indicate the most precise strategy and asterisks indicate the strategies that did not differ significantly (P < 0.05) from the best strategy. RAN, random genotyping; STD, selective genotyping; BAL, genotyping equal numbers of discordant pairs per sire; DISPAIR, genotyping of most diverse half-sib pairs; DISn, discordant sib selection with n = 10, 20, or 50 half-sib families; CONn, concordant sib selection with 5, 10, or 25 high and low sires.
