An increase in food and a decrease in predators would most
genetic variation in a population

An increase in food and a decrease in predators would most likely increase in genetic variation in the population.

Further Explanation:

In a population, the difference between the DNA sequences of an individual leads to genetic variation. Mostly in germ cell and somatic cell variation occurs due to crossing over. The variation present mostly in germ cell that is egg or sperm can be inherited to the second generation. It can affect the evolution and dynamic of a population.

The variation in a population can be in increased due to the availability of food and habitat. The natural selection requires genetic variation in a population. The different alleles can be favored due to the changing in the environment constantly.

Selective pressure can increase or decrease the genetic variation in a population. The variation in a population can be decreased due to the gene flow and due to increasing in the number of predators.

correct answer is option a.

tropopause, stratopause and mesopause have all in common aspect that is point of maximum temperature in its layer of the atmosphere. all layers of atmosphere observe abrupt change in temperature. tropopause is the boundary between troposphere and stratosphere. stratopause is the boundary between stratosphere and mesosphere. mesopause is the boundary between mesosphere and thermosphere. these all boundaries are ranges between altitude of 0 to 80 km.
