How did the polar bears get their white fur?A. Bears have various alleles for fur color ranging from dark to light. Those bears with the lighter fur had a better chance of survival in the biome, so they lived and reproduced passing on their light colored gene to their offspring. As generations passed, white fur became more common. B.As a polar bear grows up, its fur gradually gets lighter, so by the time they are a teenager, they have fully white fur and are then best suited to survive in their environment. C.Polar Bears migrated from the Pacific Northwest up to the Tundra and Arctic because they knew that they would have a better chance of surviving in this cold region.
