That striping is nothing new to me...
I originally saw it in a friend's pair of wild-caught corns. He sold me an entire clutch in 1996 and I kept 6 of them. 4 had that striping, 3 only partial body length, and 1 almost the entire body length. Both parents had a small amount of striping.
Since I was fairly new to corns back then, I considered them zigzags, and still do. The trait acts just like the zigzag gene is supposed to do...breed alot of stripe to alot of stripe and get a high percentage of striped offspring (i.e. zigzag offspring), alot of stripe to a little stripe and get a wide range of patterned, or not, offspring, and breed striped to non-related non-striped and get the occasional striped. The first couple of breeding attempts produced that wide single stripe, but in subsequent breedings, more of the "standard" zigzag pattern emerged, and just recently, the aztec pattern has shown up. I have an unrelated zigzag that will hopefully be bred to this line next year, just to prove to myself that it is trully zigzag.
More than likely, I'll bet that these babies have a family tree that merges somewhere with your aztecs.
Keep working with them, they are beautiful snakes! That amel is a definate keeper!
If I can get a decent photo
