Russo Ball Python: Genetics and Pairing Odds

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