The arctic foxes with white fur could’ve blended in more to the background and wouldn’t have been as appealing to the eye to predators. Therefore, the population of white furred foxes would carry on and the white fur gene will carry on throughout generations as long as the background doesn’t change. If the climate, conditions, or background change and they don’t camouflage anymore, they they will be more likely to get killed off and the genes will not carry on.
