Not sure how you interpretted what I meant. I actually am virtually completely unfamilliar with ball morphs, they were mentioned by someone else.
The only reason I mentioned natural/wild type is as the basis from which any kind of phenotypic differentiation can occur. The only way something can be described as different, or in this case a expressed trait, is if there is a baseline example(natural/wild type) for which other specimens can be compared to. From what I've always heard/read the "co-" of co-dom was a label for those dominant traits which had a different phenotype when in homozygous form instead of heterozygous. Granted my background is primarily cornsnakes, ratsnakes, and boa's.
I thought incomplete dominance was when a gene is dominant(het/hom) except in the pressence of certain other dominant genes in which case a phenotype differnt from either dominant gene was expressed. The incomplete dominance in this case was that neither gene fully expressed itself but the combination of partialy expressed traits created a third phenotype. If memory serves the example was cow pelt color or something.
I've always heard of two recessive genes at the same loci just being called co-allelic. In the case of ultramels it being the ultra gene and the amel gene.
Also the ultramel is not the same phenotype as amel or ultra last I heard. Ultra was a hypo form and amel is a albino form. I've never worked with them myself but I know people used to visually identify amel's from ultramel's from ultra's within the same clutch.
I have also heard from someone I trust that ultra originated somewhere else. however I don't think it affects the behavior of the gene.
I'm honestly not trying to be arguementative. I am just trying to clarify how I have generally seen it used in the past and how it is used in boa's currently. Not to mention passing allow the correction I recieved when I first inquired about ultra genetics to some of the breeders. If I am wrong or the common practices have changed then I freely accept correction/education.
