Estimates of \({M}_{e}\) in the reference population in generations 5 through 9. Estimates are derived using different methods and for different reference data sizes (\(N\)), heritabilities (\({h}^{2}\)) and numbers of sires and dams used for breeding. \({M}_{e}\) were estimated based on the Fisher or selection index (Index) approaches or based on the reciprocal of the variance of genomic minus pedigree-based relationships, with genomic relationships computed using method 1 (G1) or 2 (G2) of VanRaden [48]. Horizontal broken lines represent theoretical predictions of Me based on the effective population size (\({N}_{e}\) = 37 or 120) and the number (\(k\) = 9) and size (\(L\) = 1.5) of chromosomes based on Goddard [5] (\({M}_{e}=2{N}_{e}Lk)\) and Goddard et al. [8] (\({M}_{e}=2{N}_{e}Lk/\mathrm{l}\mathrm{n}({N}_{e}L)\)
