Since the Vanilla Cream female you have is allelic animal, she won't be able to produce any normals, only fires or vanillas, but she also won't be able to reproduce herself. It's always one or the other gene, never both in the same babies unless the second gene came from dad (like breeding a vanilla cream to a fire and getting another vanilla cream). This is because both genes reside on the same locus. It's the same idea as the BEL complex, where tons of compatible genes such as Mohave and lesser paired together produce snakes that look drastically different and who's genetics work like a super form (no normal babies) but produce two possible gene outcomes in the offspring. If you breed a Mohave lesser to a normal your clutch will be only mojaves and lessers, but never a white snake and never a normal. So basically allelic animals can't reproduce themselves in the first clutch (Zehra bred to a normal) like regular combos can. Because of this it's actually impossible to hit the 4 gene combo you want with this pairing.
Sorry for the long winded post lol. The highest gene animals you can hit on are a special firefly or a pastel vanilla special.
