An increase in food and a decrease in predators would most likely change the frequency of Genetic variation in a population.
This occurrence is more commonly known as Genetic drift which will create an imbalance in the ecosystem

Answer from: esmeraldavelez63

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.

The phlogiston theory in the 17th century attempted to explain burning. the theory stated that combustable objects contained a material called phlogiston, a substance without mass, color, odor, etc. after objects burned, the objects were dephlogistonated and were then in their true form. the phlogiston theory was accepted until the 18th century, when lavoisier proved that combustion requires a gas that has mass. phlogiston is considered a) to be scientific knowledge b) not to be scientific knowledge c) to be proven by scientific method d) to be accepted in the modern scientific community
