I understand how double and triple heterozygous forms can exist, because the genetic codes for each are in different locations, so they dont overwrite each other.

Is this true for all possible morphs? So that it is possible to have hetero or homozgyous forms for all types of morphs? Spider + Ghost + piebald for instance?

In other words, are there double and triple homozygous forms for every type of ball python that just havnt been found yet?

Double homozygous form of

albino and axanthic = snow
spider and albino = albino spider
ghost and spider = ghost spider

etc

so if there are triple forms, can there be quadruple, and so on (i know at that point it would be almost impossible to come up with, but still a chance)

quadruple homozygous forms are probably a ways off, eh ?
