Question

) There are two morphs of a certain species katydid. One is camouflaged to look like a brown, dead leaf. The other is camouflaged to look like a living, green leaf. Green color is conferred by a dominant allele, A1. The frequency of A1 on the mainland continent is 0.8, while the frequency of A1 on an island is 0.3.

What will be the frequency of A1on the island in a generation’s time, if 10% of the island population is composed of migrants from the mainland and there is no selection?

What will be the frequency of A1 on the island in a generation’s time if migrants make up 10% and the selection against green color on the islands is s = 0.25? Recognize that two genotypes are green, both of which are selected against.
