Question

A small group of people with several color-blind individuals moves from the mainland to a previously uninhabited, secluded island. Two hundred years later, 5 percent of the people of the island have color-blindness. This is an example of:​
A)​founder effects
B)​population bottleneck
C)​mutation
D)​gene flow

Quizplus · Accepted Answer

The presence of color-blindness in 5 percent of the population after 200 years suggests that a small group of individuals with the color-blindness trait founded the population on the island. This is an example of founder effects, where a small group establishes a new population and the allele frequencies of the population are based on the founding individuals. The other choices (B) population bottleneck, (C) mutation, and (D) gene flow, do not fully explain the scenario described.
