I think you would do much harder to find a normal cornsnake that has NONE of these little things going on in the pattern than finding one that has them.
I don't think that this has something to do with Aztec etc.
The animal itself is definetly not an Aztec, otherwise nearly every corn should be called Aztec.
Please also keep in mind, that the whole Aztec/ZigZag thing does not act like a dominant-recessive trait.
Hope I could help...
P.S.: You can also search for Aztec/ZigZag in the forum, I think there is more than one thread explaining what is going on with these things.
