Cumulative net present value (CNPV) of simulation scenarios, relative to the base scenario, in different selection strategies of the multiplier tier of the breeding scheme. Scenarios based on different selection strategies, described as: Pheno + GS phenotypic recording and genomic selection, Pheno + parentage phenotypic recording and parentage for pedigree selection, Pheno + GS + open phenotypic recording, genomic selection and the open nucleus, Pheno + parentage + open phenotypic recording, parentage for pedigree selection and the open nucleus, Pheno + selective GS phenotypic recording and alternative genotyping for genomic selection of physically sound candidates with potential to become replacement ewes and future only, Selective GS only genomic selection without performance recording in the multiplier by genotyping for genomic selection only physically sound candidates with potential to become replacement ewes and future rams. Phenotypic selection selection based on phenotypes only, GS only GS without performance recording in the multiplier
