A species of fox lives in the arctic where the ground is covered in white snow most of the year. These arctic foxes hunt rodents and other small mammals, while their predators include eagles, wolves, and polar bears. A mutation in its DNA causes a fox to have white fur rather than brown. Given this information, would you classify this mutation as a harmful, beneficial, or neutral mutation? Would this make the fox more or less likely to survive? Explain your answer. and make it like a 7 grader made it

The mutation that causes the arctic fox to have white fur instead of brown can be classified as a beneficial mutation. Here’s why:

  1. Camouflage: The arctic fox lives in a snowy environment, where the ground is covered in white snow most of the year. Having white fur helps the fox blend in with its surroundings. This is super important because it makes it harder for predators like eagles, wolves, and polar bears to spot them. If they can hide better, they are less likely to get eaten!

  2. Hunting: The white fur also helps the fox when it’s hunting for food. The small mammals and rodents they hunt often have fur or colors that match the snow. So, a white fox can sneak up on its prey more easily than a brown one, which would stand out against the white background.

  3. Survival: Because the white-furred fox can hide from predators and sneak up on its food better, this mutation makes the fox more likely to survive in its environment. Those that can't camouflage as well are more at risk of being caught by predators or struggling to find food.

In conclusion, the mutation for white fur is beneficial for arctic foxes, helping them survive better in their snowy habitat!

The mutation causing the arctic fox to have white fur instead of brown is a beneficial mutation because it helps the fox camouflage in the snowy environment, making it harder for predators to spot them. This increased ability to hide and hunt effectively makes the white-furred fox more likely to survive in the Arctic.
