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