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

Increase

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

Genetic variation is the differences in genes and alleles (alternate forms of gene), both within and among populations. Genetic variation may be expressed through continuous traits such as height and weight, or discrete traits such as tongue rolling. Favorable environmental factors such as an increase in food, and decrease on predators are likely to increase genetic variation in a population.

An increase in food and a decrease in predators would most likely increase 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.

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.

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.
