Super Lemon Pastel Piebald

The idea of alleles is part way between being the exact same mutation (probably most if not all the pastel lines) and being different mutations of different genes (like pastel and spider in the bee combo).

Lesser and mojave are an example of alleles - of two distinctly different mutations of the same gene. Some argue that lesser and butter might be genetically the same but lesser and mojave certainly have a genetic difference because they consistently look different even after lots of outbreeding. Also, their homozygous versions consistently look different.

The allele relationship between lesser and mojave is seen when you breed the combo snake to normal and don't get normals or combos only lesser and mojave. It was also strongly hinted at when the lesser + mojave combo was white similar to the homozygous lesser and the homozygous mojave.
