Ignore the pied stuff, look at the hets and their mom.
For those of you who don’t follow me on IG, we can skip the basic “pieds and other genes vary a lot” stuff. I’m a well established breeder and produce in excess of 100 ball pythons every year. I’ve been breeding at that pace since before MM was a thing. I work extensively with fire, vanilla, ghi, and many other highly variable genes.
No vanilla, no other known hets. She came from a close friend who’s a 30 year breeder who labeled her as a cool normal when she popped out of a pied x het pied pairing. She was bred once before I got her but produced mostly pieds so he never noticed anything odd.
As far as hets, by definition, they would not be visible if it was a recessive gene.
The reason I would like to get het pied out of the mix and see this, is because like @t_h_wyman (who saw these guys first) I believe pied a low key inc-dom so is visual to a degee.
If you look at the head stamp and pattern on the mom, it’s been inherited by the one baby posted and this other one that just shed. Ignore the pied stuff if you can’t see the difference there, look at the hets.
