Albino, lavender and caramel differences

[asplundii]

Moreover: being them different loci, if i bred a caramel x lavander i should obtain all hets for both. But what if i bred theese hets with other hets? is there a "super form" that is recessive for both?

Yes, breeding Lav x Caramel would yield offspring that are WT in appearance but double het genetically (i.e., het Lav and het Caramel). If you breed a pair of double hets together you have a 1/16 chance of a double visual Caramel Lav. To the best of my knowledge no one has done this but your outcome would be an animal that looked like an extremely faded Lav. A good example that has been done however, is the Caramel Ultramel double visual called the Camarillo.

And, as RXL mentioned, any double visual of classic Albino with one of the other albino-types morphs (e.g., Albino Caramel, Albino Lav, Albino Banana, etc.,) will look like an Albino

Double emphasize the word "assumption" there... Recently the amelanistic mutant in the corn snake, which Bechtel labelled as T-, has been sequenced. That mutant is actually OCA2 negative rather than T-. See https://www.nature.com/articles/srep17118

Yes, that paper is one of the reasons I note the assumption factor. Also the Sharpe and Kahl boa morphs appear T- but are incompatible so at least one of them must be T+. And we see the same thing with retics and burms. I have also seen a couple convincing arguments that the Albino in hognose is a T+ type.
