Agreed you are indeed guessing.

If you want to lump all generic goini in as potential hybrids that is fine but you have specifically sited blaze. I believe that to do so you should present supporting evidence beyond an uninformed guess.

Just because you do not understand the mechanism of this trait is not sufficient evidence of its origin. The fact of the matter is that blaze is a trait. It is passed on and inherited as a simple recessive. That it emerged in a line bred hi-red line of generic goini does not make it a line bred creation. My experience with the blaze trait, which is significant, is that it is not hypertheristic but some form of hypomelanism. As with many other forms of hypomelanism this trait affects both pattern elements and the intensity of melanin in the phenotype. In other words, not only is black pigment muted to varying degrees but the area occupied by melanin based pigment is also diminished. The original het blaze exhibited typical goini pattern elements. So did the F2 possible hets. Recessive traits affecting pattern elements are nothing new and shouldn’t be hard to understand.

It should also be noted that the assumption that blaze as a trait were just some sort of goini x hypo brooks cross was tested by controlled breedings and found to be false. You breed a blaze to a hypo brooks and you get double hets. To my knowledge all other types of hypo that have manifest in the FL complex have been allelic and there is no other trait out there that it is comparable too or compatible with blaze. If I’m wrong, and there are test breeding to prove me so, I’ll gracefully yield to the facts but as yet nobody including Nobody has presented anything beyond unsubstantiated and ill informed opinion.
