The mean fitness curve for an inbreeding populations with over-dominant genotype. a the mean fitness curve of the inbreeding population with selection coefficient s=0.2 and the degree of dominant h=0.2 (that is, the genotype are (1,1.4,0.8) and inbreeding coefficient f=0.25 and initial frequency x=0.1). b The detailed values in (a) from generation 12 to 52. c the curve Δ w(x) based on the change of mean-fitness in (a). d The detailed values in (c) from generation 12 to 52
