butters are caramel and amel both snakes must have these genes to produce any. Cornsnake genes are mostly recessive so to produce any morph both parents must have the same genes
any wild type is a dominant gene so if you're breeding a carolina with hets only the visual or heterozygous (genes carried not displayed) that match up with the pairing will produce visuals of whichever morphs/genes it is that match
cornsnakes, ratsnakes, bullsnakes, boas and day geckos
