Special Ball Python: Genetics and Pairing Odds

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