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, 900 Aa, 9,000 aa). If neither allele has a selective advantage, what will happen over time to the allele and genotype frequencies of these populations?

selection is not important at this locus; furthermore, the populations are no small, and hence the effects of genetic drift should not be pronounced, gene flow is occurring via the movement of pollen and seeds, thus, allele and genotype frequencies in these populations should become more similar over time, with regards to this locus, as a result of gene flow.

Explanation:

it cools slower in the earth meaning the crystals have more time to form than lava on the surface
