Suppose two plant populations exchange pollen and seeds. In one population, individuals of genotype AA are most common (9,000 AA. 900 Aa, 100 aa), while the opposite is true in the other population (100 AA, 9OOAa, 9,000 aa). If neither allele has a selective advantage, what will happen over time to the allele and genotype frequencies ofthese populations?
