Asphalt Ball Python: Genetics and Pairing Odds

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