1. Natural selection causes changes in phenotypes and genotypes of individuals within a population, which can affect the proportion of different traits in the population over time.
2. The statement that is accurate about natural selection is: "a mutation causes a specific advantage within the population."
3. The scenario of variations in fur color of mice and the predator (foxes) selectively preying on mice with white fur will likely lead to mice with brown fur becoming predominant, as they are more likely to survive and reproduce.
4. During natural selection, the phenotypes of individual organisms evolve due to their differing reproductive success based on adaptations to their environment. The proportion of different traits in a population can also evolve as advantageous traits become more prevalent over time. Inactivated genes may not necessarily evolve during natural selection unless they become reactivated due to mutations.

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?
