Mutation accumulation and fitness decline accompanying recurrent regeneration of germ plasm, with U = 5, h = 0.35, and s = 0.05. K = 50 parents for all results shown. (A) Accumulation of heterozygous and homozygous mutations in an outcrossing species. (B) Accumulation of homozygous mutations in a self-fertilizing species. (C) Fitness decline relative to initial collection in an outcrossing species. (D) Fitness decline relative to initial collection in a self-fertilizing species. Solid and dashed lines indicate bulk and equal harvesting, respectively.
