Both are hypos and when bred together or crossed, they produce a super form of the hypo.

But is the super form produced by a pair of mutant alleles? Or is it produced by the additive action of two independent dominant mutants, a double het? The only way to know is to take some of the supers from a salmon x orangetail mating and mate them to normals. If any normals show up, then the supers are double hets. I haven't heard whether this test has been done. I'd be grateful for any information you have on this point.
