There was a thread below on banded ball pythons. Normals are highly variable so you can have normals that are banded that aren't genetically reproducable. Below are pictures of what I consider Banded animals (they just so happen to be genetic too!).
These are all old pics taken in September and October. I still have all these guys here......I'll take new pics sometime.
Second Generation (F2) Banded male. Produced from Breeding my original Banded to back to one of his daughters. Out of 5 eggs I produced 1.2 Banded and 1.1 Normals.

F2 Daughter with the orginal Banded Father. The Banded father is also hypermelanistic but I don't believe that that trait is genetic.
