In a species of walruses, tusk size is controlled by a single gene that has only two alleles. The same species lives on two diff

erent sides of the Arctic Ocean. On one side, the amount of ice is much thicker and requires for walruses to have longer tusks to move out of the water. On the other side, the ice is not as thick and walruses have shorter tusks. Which of the following best describes the walruses in the two populations?
Adaptive alleles that are beneficial in one environment can be deleterious in another, due to selective pressures.
The species will eventually develop an intermediate tusk size in both populations.
The alleles of both populations will undergo directional selection to have the similar gene pools.
The species will risk decline if they continue to differ in allele frequencies and genetic diversity.
