D. Natural selection cannot occur through mutations.
Which mutation scenario will always lead to natural selection?(1 point)
A. a mutation causes a specific advantage within the population

C. a mutation causes a gene to become inactivated
D. a mutation causes a specific variation 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)
A. Mice with brown fur will be less likely to pass on their genetic information..
B. Brown fur will become predominant.
C. Mice with white fur will be more likely to survive and reproduce.
D. White fur will become predominant.
