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