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