I think co-dominanation is inconclusive with hypos. However, a super hypo will only produce hypos - even if bred to a normal. A regular hypo will produce a lot of hypos, but not all hypos, when bred to a normal. This has been proven and, therefore, supports the gene being co-dominant. However, the super form is indistinguishable from the visual het. Hypomelanism does not produce a varient super form such as BELs in ball pythons. You cannot tell the difference, visually, from a regular hypo and a super hypo. The super form has to bred in order to be proven.
Hypomelanism is widely accepted in the boa community as co-dominant. I wouldn't worry about treating it in any other way until it is proven otherwise - and that goes for any other gene that is difficult to determine. Of course, we want to be as accurate as possible, but there is only so much we can do with the little information we have.![]()
