Average prediction accuracy $rg,g^$ in selection cycle $C=0$ for different numbers of recombination generations $NR$ used for production of synthetics from $Np=2,4,16$ parents taken from ancestral populations SR or LR. LD_A, ancestral linkage disequilibrium; LE_A, ; LR, long-range linkage disequilibrium; Ped, pedigree; Re, related; SNP, single nucleotide polymorphism; SR, short-range linkage disequilibrium.
