Recessive

Whenever I show someone a picture of an axanthic ball python, the conversation is always the same: "It's a black and white picture of a snake. So what?"

So everything!

This simple recessive mutation eliminates the yellow and/or red pigments, leaving an animal with normal patterns and contrast, but cast entirely in shades of grey, black and brown. When combined with a pattern mutation, the axanthic mutation creates a whole host of stunning, grayscale animals that look more like filtered photographs than real snakes.  Amazing!
