What Is An Ultramel???

There are two mutants at the amel locus, as well as the wild type.
Alleles:
A<sup>+</sup> = wild-type allele
a<sup>a</sup> = amel allele
a<sup>u</sup> = ultra allele
These can be present in an individual snake in any of the following 6 genotypes, which produce the 4 phenotypes known as normal, amel, ultramel, and ultra.
Genotype/phenotype key:
A<sup>+</sup>·A<sup>+</sup> (Normal)
A<sup>+</sup>·a<sup>a</sup> (Normal het amel)
A<sup>+</sup>·a<sup>u</sup> (Normal het ultra)
a<sup>a</sup>·a<sup>a</sup> (Amelanistic)
a<sup>a</sup>·a<sup>u</sup> (Ultramel)
a<sup>u</sup>·a<sup>u</sup> (Ultra)

yeah..to say the least. LOL. it is a combonation of the ultra hypo gene and amel. they are working on the same allele. it acts as an incomplete dominant trait. if you do a search there are many threads that have over a hundred posts on each to describe and to show the "mystery" as it unravelled.

The ultramels have ruby pupils, at least when they hatch. It appears that some pigment can accumulate in the eyes so that they lose the ruby glow by maturity. (This also happens with one of the "hypo" traits in rats.)
The ultras presumably look like regular hypos, there haven't really been that many proven to be homozygous. However, if you take amel as being a non-functioning gene and ultra as having a little function, I'd expect ultras to basically have twice as much melanin as ultramels.

It's something that absolutely requires knowing the basics. If you have the basics and know what locus/allele are, it is very plain to see. Otherwise, it will always sound confusing. It'll never make sense without that foundation. It would be like trying to understand fractions without ever learning how to count... ain't gonna happen.
