Question

Which environmental factor would likely lead to an increase in genetic variation in a population of squirrels?

Answer 1

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.

Answer 2

B. an increase in available food. 


IT cannot be A, C, D because it would hurt the species' population.
