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

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

Further Explanation:

In a population, the variation between the sequences of DNA of an individual can leads to the variation in genes. Mostly in somatic and germ cell variation can occurs because of the crossing over. The difference in genes mainly present in the germ cell that is sperm or egg that can pass to the second generation. It can influence the dynamic and evolution of a population.

The difference in a population can be increased due to the ease in habitat and food. The natural selection requires variation in genes of a population. The different alleles can be favored because of the change in environment constantly.

Selective pressure can decrease or increase 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. Thus, the genetic variation increases due to decrease and increase in predators and food respectively.

explanation:

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
