The mutation that results in a mouse with less light fur as compare to other mice of same population, makes it easier for the mice to blend into their surrounding environment. According to law of natural selection, if a genetic mutation is beneficial for a population, the mutated organism survives to reproduce and that mutation gets transferred on to its offspring.
Thus, the correct answer is 'option). the mouse with the genetic mutation will survive and reproduce, and the trait (for fur) will spread over future generations.'
