Answer from: EmiHope

The correct answer is an increase.

Increase in food and decrease in predators will lead to increase genetic variation in a population. Genetic variation means that biological systems such as population and individuals are very different over space.

The variation occurs among populations which are being supported by individual carriers of the variant gene. Genetic variation is brought about by a mutation which is a permanent change which is found in the chemical structure of chromosomes.

Answer from: Theacefamily123

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.

Listed in the item bank are some key terms and expressions associated with the categories seen in the venn diagram. to find out more information about items, some have more details available when you click on them. drag and drop each item onto the proper area of the diagram. if an item describes more than one category, be sure to place it in the overlapping space. viruses are tiny infectious pathogens that cause many different diseases, such as polio, and the flu. though they are similar to one celled organisms in some ways, in many ways they are very different. use the venn diagram below to show the similarities and differences between viruses and living organisms.
