Please explain the reasoning of the answer for both questions.
Thank you

Question 1 (5 points) In the absence of mutation, genetic, drift, and any other forces that would generate genetic variation in a population, the eventual result of time, measured in generations is: a. Nothing, there is no change in a population without the factors mentioned above. b. Variation will increase if the effective population size is large enough. c. All variation will be lost from the population no matter what the size of the population is. Question 2 (5 points) In a population in which the effective population size is large, the loss, gain, or change in genetic variation a. Is small in any one generation, and with a large population that means that even loss of variation would be slight and therefore variation would persist for many generations. b. Effective population size is immaterial to genetic change. c. This depends on the size of the founder population and the spread of that population over a geographic area. It is the size of the geographic area that determines the change in the genetic variation.
