Batches of 1000 ten-locus genotypes were constructed as random samples from infinite populations at selfing equilibrium (s = 0.05, 0.1 and 0.3).
In an infinite population with partial full-sib mating, it has been shown that [[Alpha].sub.I,s] = [[Alpha].sub.o] = [Beta]/(4 - 3[Beta]) (Hedrick and Cockerham 1986), where [Beta] is the proportion of full sib mating.
Second, we can simulate an infinite population exchanging a finite number [M.sub.o] of immigrants each generation simply by following the increasing but finite number J of individuals which possess any amount of immigrant material.
As an example, consider an infinite population of diploid hermaphrodites, organized into discrete patches of 200 individuals.
Because with an infinite number of loci every new mutation is unique, outcrossing to an unrelated individual in an infinite population never produces homozygosity of mutant alleles.
