From: Genome-wide deleterious mutation favors dispersal and species integrity
Population-level advantage to migrants under various levels of mutation and migration. Calculations assume an infinite number of demes with N = 1000 each. Fitness is determined by genomic mutation at rate U to deleterious (h = 0.1, s = 0.1) alleles at n = 10,000 loci. The panels show total number of mutations per gamete, n̄, population average fitness, w, local inbreeding depression (1 − W̄inbred/W̄local), and average fitness of offspring of migrant compared to local parents (wmigrant/wlocal).
