Verified
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
Founder Effects
A form of genetic drift that occurs when a new population is established by a very small number of individuals from a larger population, leading to limited genetic variation.
Color-Blindness
A deficiency in the way someone sees color, making it difficult to distinguish certain shades of color, typically red and green.
Population Bottleneck
A significant reduction in the size of a population due to environmental events (such as earthquakes, floods, fires, disease, or droughts) leading to a loss of genetic diversity.

Final Answer :
A
Explanation :
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.
