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