The effect overfishing most likely have on a population of fish in a lake is to create a bottleneck effect, reducing genetic diversity.
Option B is correct
Overfishing can have a significant impact on the genetic diversity of a fish population. When a large number of fish are removed from a population, the remaining fish represent a smaller sample of the original gene pool. This can lead to a loss of genetic diversity, which can make the population more susceptible to disease and other threats.
Option A is incorrect because gene flow is the movement of genes between population as overfishing does not directly cause gene flow.
Option C is incorrect because the founder effect is a reduction in genetic diversity that occurs when a small number of individuals colonize a new area. Overfishing does not create a new population of fish.
