i think there are variables in the environment that could be at play. for example, temp spikes during incubation could have an impact. how did u incubate, what temps and for how long?
IIRC there is an incomplete dominant trait called Whitewash that creates a paradox like effect. this is different from your animals or mine or anyone else's which is unexplainable w/ current genetics. i think u should give your Butter girl time off and try for another paradox in a year or two. try pairing he to another BEL animal? maybe Mojave this time? it would be a true jackpot if she proves 3 in a row.
Edit:
yeah, i wouldn't call that paradoxing. Super Cinny's are known for their splotching and flecking. it becomes more obvious when u add Albino to make a Cue Ball (or Blizzard) when u have a white snake w/ just yellow/orange splotches and flecks. my friend Taylor has a Super Cinny w/ what i believe is true paradoxing. it's small but it's there towards the tail: https://ball-pythons.net/forums/show...ression-thread
