Why is the fur of Kermode spirit bears so different from American black bears, even though they are a subspecies?

Answer :

Final answer:

Kermode spirit bears have different fur from American black bears due to a recessive gene that causes a pigmentation variation.

Explanation:

The fur of Kermode spirit bears is different from that of American black bears because of their genetic makeup. Kermode bears, also known as spirit bears, are a unique subspecies of black bear that have a white or cream-colored fur due to a recessive gene. This gene, known as the KIT gene, causes a pigmentation variation in their fur color. In contrast, American black bears have a range of fur colors, including black, brown, and cinnamon, but not white or cream.

The variation in fur color between these two bear subspecies is an example of genetic adaptation in response to their different habitats. Kermode spirit bears are primarily found in the coastal rainforests of western Canada, where their white fur provides camouflage in snowy or icy environments. American black bears, on the other hand, inhabit a variety of habitats across North America, including forests, mountains, and swamps, where their fur color helps them blend in with their surroundings.
