There are two populations of mice. One is large and lives on the mainland. The other is small and inhabits an island. The two populations exchange migrants at a high rate across shallow water that connects the island to the mainland. Part A If you compared the allele frequencies in the two populations, what would you expect to find? If you compared the allele frequencies in the two populations, what would you expect to find? the allele frequencies of both populations are likely to be similar. the allele frequencies of both populations are completely different. the allele frequencies of both populations are exactly the same.
