The Mystic ball python is a co-dominant morph. It is common belief that the mystic is the same genetics as a phantom, proven by Ralph Davis. Only time and breeding tests will tell.
The mystic looks like a darker Mojave Sort of a black with burnt orange highlights.
Mystics carry the same allele as the Mojave, lesser platinum, and butter but somehow the result is quite different.
By breeding a Mystic/Phantom to a Mojave you have a 25% chance of hitting on a Mystic Potion. The Mystic Potion is an awesome mixture of subtle purple, gray and pink markings.
In future mystic breeding projects, I hope to hatch one or more Mystic Spiders, and likely Super Mystics as well.
