SciShow: The Delightful Mutation Behind Siamese Cats

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: It's easy to assume a cat's coat pattern is based exclusively on genetics, but that isn't entirely the case for Siamese cats. Their unique coloration comes from a combination of genetics, a fragile enzyme, and losing heat from little noses and toe beans. Hosted by: Hank Green SciShow has a spinoff podcast!
