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?

One likely consequence of this scenario is that over time, the population of mice with white fur will decrease while the population of mice with dark fur will increase. This is because the mice with white fur are more easily caught by foxes, which means they have a lower chance of survival and reproducing compared to the mice with dark fur. As a result, the genes for white fur may become less prevalent in the overall mouse population, while the genes for dark fur may become more prevalent as they provide a survival advantage. This is an example of natural selection favoring traits that increase the chances of survival and reproduction.
