I'd suspect you would produce babies like that consistantly from that female. Brian Gundy does it every year with his Gold Blush Mojave line... Those normals of his throw some spectacular looking mojaves. His mojaves don't look like anyone elses. So it would not surprise me one bit if that female throws a specific look or even color... it's called a normals gene pool, some are better than others.
I seriously do wish you the best of luck proving that female to be genetic, I just won't agree that she is after seeing the results of one clutch. I wasn't trying to talk down to you in any way when I made my post. I'm simply making the point that no breeder I know would put his reputation on the line after hatching one clutch. That's all I'm saying. You on the other hand seem to be hell bent that she's genetic and you know it without a shadow of a doubt. I just hope for your reputations sake she really is. I think posting the photos of the normals may have actually hurt your story here too, because from the looks of it only one looks like a black back and even it isn't a very good example. The other two just look like standard normals. I really don't mean that to sound derogitory, they just do. Sorry. I've seen way to many good looking normals hatch to buy into it after only one clutch. But in no way am I saying your female can't be genetic or that you are wrong. I'm just saying that I wouldn't buy into it after seeing only one clutch from her is all. After 3 or 4 of the same consistant look or even producing a super, then I'd buy it. Or maybe if you bred her to a normal and got GBB's and normals. If it's genetic they would look different right? Well then you would know for sure. But after putting her to a cinnamon and making black back cinnamons, doesn't really prove anything. And like I said only one of those normals looks like a GBB possibility to me. Maybe 2, but even the second one is far from even being blushed 1/2 way. So probably not there either. The color thing doens't always mean genetic either, normals can look bunches of different ways. And normals bred to morphs can make unique looking morphs (Brian Gundy is the perfect example).
Here are a couple of pics just to show you how much normals can vary.
Pic #1 - Sire: Spotnose + POG Dam: Normal - None of these parents are GBB's nor do any of them have much or any dorsal blushing. And not to boast but this animal looks better than 2 of your 3 GBB's you posted and it's not.
Pic #2 and #3 - Sire: 100% Het Albino Dam: 100% Het Albino - Neither of these animals are as light as this female 66% het that I hatched. She looks to me like a vannila, but she's not, she's just a normal. Her brother looks just like mom and dad. (female left - male right **both pics**)
