I've got some from my homozygous pied colony like that. Mine tend to be a lower white pied compared to some I saw from another colony but I get a few of the ones with lots of white too. I've only just set up my first cross colony group to produce the heterozygous pieds so I don't have personal experience with how they look but it's sounding like there might be some overlap between the highest white hets (gremlins) and the lowest white homozygous pieds with this co-dominant mutation. Sort of like how ever once in a while someone has to ask if a baby from a pastel X pastel ball python breeding is a super pastel or not.
