A pale box is an animal that shows the morph. These are the odds for each egg on its own, not a promise about a clutch.
What this rests on
Established by breeders through repeated crosses and recorded in community documentation, not by published genetics. That is how almost all morph inheritance is known — and it is worth saying rather than presenting it as laboratory fact.
What happens if you breed it
Every pairing involving Anerythristic, worked out gene by gene — including what the clutch can be and anything documented about the animals it produces.
