What effect would overfishing most likely have on a population of fish in a lake? a-cause a gene flow to occur in the population. b-create a bottleneck effect, reducing genetic diversity. c-create a founder effect, restricting genetic variation. d-increase the chances of mating between non related partners. e-favor the process of stabilizing selection in the population.

The right answer is B- create a bottleneck effect, reducing genetic diversity.

A population bottleneck (also known as a genetic bottleneck) is, in the study of biological evolution, an event corresponding to the fact that a substantial proportion of the population of a species disappears or is prevented from to reproduce.

Population bottlenecks (or bottlenecks) thus reduce genetic diversity, and hence the ability of people to adapt to new environmental constraints such as climate change, or a decline in available resources.

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
