Which genetic process is LEAST likely to add a variety of new traits to an individual?

3

A population of ferns is exposed to the same amount of a toxic chemical and only a few of the mushrooms survive. What is the best explanation for the resistance of some of the mushrooms to the chemical's effects?

Imagine there are 3 populations of snow hares. Snow hares have different colored fur ranging from white to brown. White snow hares can hide from predators more easily in the snow, and light brown snow hares can hide more easily in the grass and brush when the snow melts. Which of these populations of snow hares is most likely to survive this a winter with constantly changing weather and unpredictable snow?

Population 1: All the snow hares are completely white
Population 2: Most of the snow hares are completely white, but some of them have brown splotches.
Population 3: There are many snow hares of all different colors from completely white to completely brown.
