In the scenario depicted in the figure, what will happen to the allele frequencies on the island? Assume there is no selection or mutation, mating is random, and the population sizes are large. A) They will become more similar to those on the mainland. B) They will remain at their current frequencies. C) The A₂ allele will go to fixation. D) We cannot predict how the allele frequencies will change.
