EH_M = expected heterozygosity obtained when management is based on molecular data, EH_M-G = expected heterozygosity obtained when management is based on genealogical data, expressed as a deviation from EH_M, d = SNP density expressed in SNP/Morgan, N_e = effective population size, t = generation; ^amolecular coancestry was calculated using the non-marker loci.
