Genetic gain (ΔG), rate of inbreeding based on pedigree (ΔFped) and on genomic IBD (ΔFIBD) relationship matrices at generation G10 when the constraint on relationship was either pedigree-based (ΔFA) or marker-based (ΔFG) with TBLUP or GBLUP breeding value estimatesa.
aNtest = number of test sibs; ΔFd = desired rates of inbreeding; number of selection candidates = 3000.
