First, it is called a hypo, but that doesn't mean it is biochemically just a hypo. You are correct if the trrait was JUST a reduction in black. Apparently, it does more than that - or something different that LOOKS like what a hypo would do.
>>That was always the general opinion until Don Soderberg (SMR)and Jim Stepflug (SWReptiles) both started producing Hypo Snows every year and proved the hypo gene does make a visual difference in Snow corns.
Second, it really is a little more complex than that. Not all Hypo snows are anything line a "pink" or "coral" snow. Sone of the brightest pink ones aren't hypos, too. Soooo, simplification can be a problem in this situation. Is it due to the varying strains of hypo? I don't know. Is it due to natural variation as is seen in hypo and other traits? I don't know, but probably.
Sooooo, not all hypo snows are "pink snows" and not all pink snows are hypos. however, I don't disagree with your statement concerning Don's/Jim's situation. I have never heard anything to contradict what you stated, of course.
BUT, don't think just getting a hypo snow is all that is necessary to get a coral or pink snow.
