Question 4
A)
Consider the following scenario:
There are variations in the fur color of mice. Some mice have white fur. Some have dark fur. Foxes more easily catch mice with white fur.
What will likely be a consequence of this scenario?

Responses
White fur will become predominant.
White fur will become predominant.
Mice with white fur will be more likely to survive and reproduce.

Thank you for the update. I apologize for the oversight in the responses. The correct consequence of the scenario would be:
Brown fur will become predominant.
