Interesting question, Matt. With all of the base morphs having come from the wild, and proven genetic, I have to wonder if any really crazy color or pattern mophs have been captured and sold, but not proven to be genetic? Like a one of a kind that can't reproduce it's self but is sitting is some breeder's collection somewhere.
I remember a couple of years back seeing a picture of a wild caught BP male that had a normal type pattern, but was the color of a glass of Merlot wine. It was stunning, but I haven't seen anything like it since. I can only guess that it wasn't genetic.
There is a few breeders with some ball pythons that are the first of their kind on this planet. They might keep it on hush if they cant figured out the genes or if there trying to as we speak.
