A population of finches on an oceanic island varies at a particular gene locus. The current allele frequency is A1 = 40%, A2 = 60%, and there are 12,000 birds on the island. On the nearest continental mainland, the same species is monomorphic for allele A1. If 3,000 birds migrate from the mainland to the island, by how much will the frequency of allele A1 change on the island?
