The genes that determine the length, pattern, coloration, and texture of a cat’s fur are so complex that, theoretically, a practically countless number of distinct coats could be generated.

Some coloration is temperature-sensitive, creating cats that have darker fur on the tips of their bodies, where fur is cooler. Which type of cat looks like it has an M on its forehead? Discuss
