Answer:
The most likely difference in mouse populations in locations with dark backgrounds compared to light backgrounds is:
Fur color
Explanation:
Here's why:
Camouflage: Animals often have adaptations that help them blend into their environment. In this case, darker fur would be beneficial for camouflage in dark environments, while lighter fur would be advantageous in light environments. This helps mice avoid predators.
Natural Selection: Over generations, mice with fur color that better camouflages them in their environment are more likely to survive and reproduce. This can lead to populations where the dominant fur color matches the background.
Body size, tail length, and eye color, while potentially having variations within mouse populations, are less likely to be directly influenced by background color for camouflage purposes.
