Questions About Producing Super Ball Hybrids

Agreed, I was being very general in my speaking. I made the assumption even if both were tneg that there would be a great possibility it would not be on the same locus and therefor unlikely to create the visual. ...

The amelanistic mutant gene in corn snakes tests as T-negative albino with the dopa test, but it is actually a nonfunctional version of the OCA2 gene. (T-negative means the gene is a nonfunctional version of the gene that produces the tyrosinase enzyme. OCA2 stands for oculo-cutaneous albinism 2.) So there you have two "T-negative" mutant genes that have different locations in the cell nucleus.

I am not aware of any boa or python albino mutations that have had the dopa test or any other biochemical tests run. When used with boas and pythons, T-negative albino generally means no visible black pigment (melanin). T-positive albino means some melanin but less than normal. That leaves a good bit of room for error.
