Which mutation scenario will always lead to natural selection? (1 point)
• a mutation causes a specific advantage within the population
O a mutation causes a specific variation within the population

• a mutation causes an inactivated gene to be reactivated

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