If a mutation creates a new fur color in a wolf population, what factor might determine whether the frequency of the new trait will go up

Usually, when mutations cause major changes in the external appearance of a population, the selection mode is how well that new color blends in with its environment. It it blends well, the animal will be hidden better from predators and survive.

The answer is atmosphere. there are four spheres of the earth: 1. geosphere (from greek word 'geo' = ground), 2. hydrosphere (from greek word 'hydro' = water), 3. biosphere (from greek word 'bio' = life), and 4. atmosphere (from greek word 'atmo' = air). a magnetosphere is a region of space around astronomical objects controlled by the magnetic field of that object. through the process of elimination, since lightning is present in the air, it can be found in the atmosphere.
