Rates of genetic gain (ΔG) and inbreeding (ΔF) realized by genomic selection as a function of male-to-female genotyping ratio at 8 genotyping proportions with the reliability for direct-genomic values at 0.50. Each point represents the mean of 100 replicates. Standard deviations of the means ranged from 0.01 to 0.02 for the rates of genetic gain and 0.003 to 0.005 for the rates of inbreeding. The horizontal lines are rates of genetic gain and inbreeding with 0 and 100% genotyping.
