Which mutation scenario will always lead to natural selection? (1 point)

Question

a mutation causes a gene to become inactivated
a mutation causes an inactivated gene to be reactivated
a mutation causes a specific variation within the population
a mutation causes a specific advantage within the population

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?

(1 point)

Brown fur will become predominant
White fur will become predominant.
Mice with white fur will be more likely to survive and reproduce.
Mice with brown fur will be less likely to pass on their genetic information.

What evolves during natural selection? (1 point)

inactivated genes

the phenotypes of individual organisms

the proportion of different traits in a population

entire species
