For a diploid species, assume one set of 100 demes, each with a constant size of 50 individuals, and another set of 100 demes, each with 100 individuals. (a) If in each deme the frequencies of neutral alleles A1 and A2 are 0.4 and 0.6 respectively, what fraction of demes in each set is likely to become fixed for allele A1 versus A2?
