Phenotypically...looks like a corn, fun pattern at that.
Genotypically, well you could try to find a university lab to take either a blood or scale sample and then have them process it against mtDNA and nDNA. Keeping this super simplistic, mtDNA, or Mitochondrial DNA will show markers maternal genetics, while nDNA, or Nuclear DNA, is used for showing markers for paternal genetics.
Thoughts: Looks like a corn snake that possibly has a lineage that ties back to zigzag/Aztec/funky blotch animals. Or it could be random and/or the result of askewed incubation temps. In my experience, jacked incubation temps has resulted in catastrophic deformities (severe kinking, odd head formation, all offspring died in egg or shortly after pipping) and is thankfully something I've not experienced since 2002. I had some seriously messed up snow corns and great plains rat snakes from my "female leopard gecko" incubator spiking to 88°F; it was supposed to be at 82.
