Answer:

a) Founder effect

Explanation:

Founder effect: Small group of individuals separates from large population, and establishes a colony in a new place. Smaller new population won't have as much genetic variation as original, larger population.The allelle frequencies in the new population will be different than the original population.

For example: Few people leave a population and become founders of separate island.

As in the given scenario,Founder effect is the most likely explanation for this pattern.
