Phantom Ball Python: Genetics and Pairing Odds

Phantom is a co-dominant (incomplete dominant) gene. One copy gives the Phantom look, and two copies make the Super Phantom, a stronger version of it. Bred to a normal, a Phantom gives about half Phantom babies; a Super Phantom gives Phantom babies every time.
