there is no guarantee with that breeding.
if I had a female mystic or phantom up to breeding size, I wouldn't waste her on a male mojave. not when a super phantom/ mystic are going for 5500 and you can pick up a mystic/ phantom male for around 500 to breed to her.
I produced 2 mojave x lesser bels and a mojave x mojave bel last year. I like both the very clean look and also the super mojave look. I still have the super mojave, it's a very strong genetic snake to have in a collection.
