Mostly I agree with this. Rarely there can be a third chromosome, though (see the link for an example in humans). If this is the cause of the red devil, then expect them to be born dead or not survive long.

I would be delighted if motley and salmon had the same locus (position in a chromosome). But I have to play devil's advocate. Without seeing numbers, I don't think we can eliminate the chance of linkage yet. That would place the motley locus close to the salmon locus. If the motley mutant gene was in the chromosome from one parent of a hypo motley, and the salmon mutant gene was in the chromosome from the other parent, then most of the babies from a hypo motley X normal would be either hypo or motley. I'd like a couple of hundred babies from hypo motley X normal or similar matings.
