Question
A population of mice that live in an area with dark rocks have more black mice than brown mice because brown mice are an easy prey, Duo to a change in the climatic condition, the mice migrate to an area with light-colored rocks. What will MOST LIKELY happen to this population over a few generations after migration? Select TWO correct answers. A. Brown mice will have a higher chance of producing offspring. B. There will be more black mice than brown mice. C. There will be more brown mice than black mice. D. The population of mice will become zero. E. The population of mice will remain the samo. E. Black mice will have a higher chance of producing offspring.

Answer
A. Brown mice will have a higher chance of producing offspring.C. There will be more brown mice than black mice.
Explanation
The scenario described involves a population of mice that originally lived in an area with dark rocks, where black mice had a survival advantage over brown mice due to better camouflage from predators. With the migration to an area with light-colored rocks, the selective pressures on the mice population will change. In the new environment with light-colored rocks, brown mice will likely have better camouflage than black mice, making them less visible to predators. This change in camouflage effectiveness will affect the survival and reproduction rates of the two color morphs.Over several generations, natural selection will favor the brown mice because they are less likely to be preyed upon. Consequently, brown mice will have a higher chance of surviving to reproductive age and producing offspring. This shift in selective pressure will lead to an increase in the proportion of brown mice in the population.Given these considerations, the most likely outcomes over a few generations are:- Brown mice will have a higher chance of producing offspring.- There will be more brown mice than black mice.
