Results are given for different cases, each characterized by the effective sizes after population shrinkage (N), the deleterious mutation rate (λ), the mean and shape parameter of the gamma distribution for s (E(s) and “Shape”) and the average dominance coefficient (E(h). δ and δ* are, respectively, the inbreeding depression rates at the ancestral an the new MSD balance under no management.
Increase of the relative expressed segregating load ascribed to EFC. Regular font: bounded prediction computed from Equation B2; Italic font: unbounded prediction computed from Equation B1a, given only when larger than the MS bound.
