Consider a mainland-island migration scenario where two alleles are segregating and the observed frequencies of heterozygotes are such that Hi = 0.32 for the mainland and Hi = 0.5 for the island. What are P(island) and P(mainland)? Assume very large population sizes, no inbreeding, and the other assumptions of H-W […]
