Explanation:

In a very cold winter, if a wolf is not well - adapted (e.g., lacks thick fur for insulation), it would face harsh conditions. Natural selection acts against individuals that are not fit for the environment. A wolf that cannot survive the cold would likely die before reproducing. This is in line with the principles of natural selection where unfit individuals are selected against.

Answer:

It would be selected against and would likely die off before being able to reproduce.
