Which environmental factor would likely lead to an increase in genetic variation in a population of squirrels? a. an increase in predators b. an increase in available food c. an increase in forest fires d. an increase in pollution

Answer is: B. an increase in available food.

Genetic variation is important to the population's ability to survive in different situations that affect natural selection. New habitat and increased food supply can increase genetic variation.

The environment is constantly changing and different alleles are favored.

An increase in predator, forest fires and polltion will decrease genetic variation in a population of squirrels.
