which environmental factor would likely lead to an increase in genetic variation in a population of squirrels?\n○ an increase in predators\n○ an increase in available food\n○ an increase in forest fires\n○ an increase in pollution
Answer
Brief Explanations:
An increase in available food provides more resources for the squirrel population. With more resources, there is less competition for survival. This allows for a larger population size, and a larger population has a greater chance of genetic mutations occurring and being passed on, thus increasing genetic variation. An increase in predators, forest - fires, and pollution typically cause stress and high mortality rates, which can reduce genetic variation rather than increase it.
Answer:
an increase in available food
