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?
A. Mice with white fur will be more likely to survive and reproduce.
B. Mice with brown fur will be less likely to pass on their genetic information.
C. White fur will become predominant.
D. Brown fur will become predominant.
A. Mice with white fur will be more likely to survive and reproduce.
What evolves during natural selection?
A. entire species
B. the phenotypes of individual organisms
C. inactivated genes
D. the proportion of different traits in a population
