Everyone always distinguishes between a 100% "normal" and a: Pastel, Albino, etc. I understand how those genetic traits come about that classifies these animals as such. However, I have a discrepancy with people saying there are many different variations of "NORMAL" Ball Pythons.

Obviously, the genetics account for these variations (or abnormalities) in these "normal" ball pythons. Surely, in regards to dogs in particular, you have heard of the "Mutt." A Mutt is not just a "fancy normal dog," it is a mixture of the genetics of two different pure bred breeds of dogs, or even a mix of many different breeds.

So, explain to me how a "normal" Ball Python can't be, say, 25% Pastel and 75% Normal.
