due to finite sampling. We can also see this by noting that 2 m genotypes heterozygous and m2 genotypes homozygous for alleles entering the subpopulation by gene flow are expected each generation. Together, these two classes of genotypes bearing alleles that entered the population by gene flow reduce the auto-zygosity by a factor of 1 - 2m - m2 = (1 - m)2. This 1 2

gives-(1 - m)2 as the autozygosity adjusted for

2Ne gene flow. Using the same reasoning, the chances that a randomly sampled pair of alleles in a subpopulation are autozygous due to past inbreeding
