Gravel Ball Python: Genetics and Pairing Odds

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