Lesser Ball Python: Genetics and Pairing Odds

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