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?

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

Mice with brown fur will be less likely to pass on their genetic information.
Mice with brown fur will be less likely to pass on their genetic information. - no response given

Mice with white fur will be more likely to survive and reproduce.
Mice with white fur will be more likely to survive and reproduce. - incorrect

Brown fur will become predominant.
Brown fur will become predominant. - not selected, this is the correct answer

White fur will become predominant.
White fur will become predominant. - no response given

Mice with white fur would not have a higher probability of surviving and reproducing.

Answer 5

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.
