Apopulation of snakes that eat small rodents enters a new habitat. in the new habitat, there are many species of rodents, and their populations are high because there are few natural predators. what will most likely be the effect on the genetic variation of the snake population? genetic variation will increase because of a selective pressure. genetic variation will increase because of a new habitat and food source. genetic variation will decrease because of a selective pressure. genetic variation will decrease because of a new habitat and food source.

Answer:  Genetic variation will increase because of a new habitat and food source.

Explanation:

Genetic variation means the naturally occurring genetic differences that exist between the individuals of the same species.Genetic variation is important as it allows the individuals to survive better in a given environment. When the snakes enter a new habitat they are in the scenario where there are few natural predators. Due to this they have plenty of food and less competition. Thus, there is no selective pressure that exists to influence the genetic variation.Further, in the absence of competition and abundance of food, the genetic variation will only increase.So, in the given case the genetic variation of the snakes increases due to new habitat and food source.

The return of the wolf to yellowstone national park will probably affect the bird population to some degree, not significantly. while wolves will hunt birds when necessary, they prefer to hunt larger prey. the bird population will most likely only be affected when hunting is scarce for the wolves. birds of prey will also probably not be affected as much as other birds who spend more time on the ground hunting for food as the tend to spend more time in the air or in trees since they do not need to stay on the ground for long due to the nature of the way they hunt.
