Answer:
The snowshoe hares with mutated genes for fur colour
Explanation:
As we can see in the question that change in fur colour in response to day length is a normal adaptation in the snowshoe hares. But due to climate change the less snow fall occurs and thus white fur hares will be visible to the predators. If some of the snowshoe hares have mutated genes for the fur colour in their cells then they will be prevented from the predation because this mutated gene can cause the change in fur colour in response to the change in temperature in place of change in day length and thus such hares with mutated gene will survive safely in changed climatic conditions.
