Determine which process of evolution is likely impacting the population below. Once you have determined which process of evolution is likely occurring for each problem, briefly explain why you selected that process.

1. The inhabitants of the island Trinity are all descended from one indigenous family and a few colonists. Violet eyes are much more common among these islanders than in any other human population. It is assumed that at least one of the original island settlers carried this rare allele. The violet eye disorder has an abnormally high frequency among this small population because many can trace descent to at least one member of the small group of colonists.

Which process of evolution likely affected this population in regards to the rare violet eye color allele? Explain your reasoning.

Final answer:

Genetic drift is impacting the island population due to the founder effect and small population size resulting in a high frequency of the violet eye color allele.


Explanation:

Genetic drift is likely impacting the population on the island Trinity in regards to the rare violet eye color allele. This is because the high frequency of violet eyes among the islanders is due to the small population size and the founder effect, where the allele was present in the original colonists and became more prevalent through chance rather than natural selection.
