In the Figure Below,the Migrating Bird Is Successful at Introducing

In the figure below,the migrating bird is successful at introducing the recessive allele a into population 2 and producing offspring with the Aa genotype.Over time,these offspring mate with each other to produce offspring.Birds of various genotypes from both populations fly back and forth between the populations sharing alleles.Predict the outcome of genotype or allele frequency changes in these two populations after many generations.
