If a new morph comes along, we would not know how the gene works if someone just said "it's allelic".
Here is how we would know that how toffino works. Toffee and albino are alleles. The toffee mutant gene is recessive to the normal allele. The albino mutant gene is recessive to the normal gene. The albino mutant gene is codominant to the toffee mutant gene. A toffino snake has a toffee mutant gene paired with an albino mutant gene.
A snake can have one of the following gene pairs:
2 normal genes -- snake is normal and looks normal
toffee mutant gene and normal gene -- snake looks normal
albino mutant gene and normal gene -- snake looks normal
two toffee mutant genes -- snake has toffee appearance
two albino mutant genes -- snake has albino appearance
albino mutant gene and toffee mutant gene -- snake has toffino appearance.
Here is how we would know that how lesser and mojave work. The lesser and mojave mutant genes are alleles. The lesser mutant gene is codominant to the normal allele. The mojave mutant gene is codominant to the normal gene. The lesser mutant gene is dominant to the mojave mutant gene.
A snake can have one of the following gene pairs:
2 normal genes -- snake is normal and looks normal
lesser mutant gene and normal gene -- snake is a lesser platinum
mojave mutant gene and normal gene -- snake is a mojave
two lesser mutant genes -- snake is a blue-eyed leucistic (BEL)
two mojave mutant genes -- snake is nearly white with some pigment on top of head and neck.
lesser mutant gene and mojave mutant gene -- snake is a BEL, like a snake with two lesser mutant genes
Plug the genotypes into a mating and apply the appearances to the offspring for any mating you care to make.
