Not quite sure what you're asking.

Basically, Tremper albino is its own gene, so it would presumably have its own allele allocation. I do not believe this has been given a formal name. I suppose if I were writing it down for a Punnett square I'd call it a/a (Amelanistic) as it was the first amelanistic-type gene discovered. "Chocolate" is NOT a genetic thing - it's related to incubation temperatures. Any albino can be made into a "chocolate" by incubating the eggs at a lower temperature and/or by keeping the hatchlings with a lower basking temperature.

Amelanistic corns have been labeled a/a (as amel is recessive to wildtype A) although if these are ever formally named it's quite possible the gene locus will be renamed C (to go with the albino locus on mammals).

A "Het Coral Snow" is heterozygous for Amelanistic, Hypo and Anerythristic - I would personally call this A/a E/e H/h (Amel, anErythristic, Hypo) though you may see others use A/a An/an H/h. I prefer to avoid using double letters to denote genes where possible.

And I don't think anyone's done enough testing to find out what the exact heritability of "flame" is on crested geckos (dominant, recessive, codominant, polygenic selectively bred) ... so no idea there
