VPI AXANTHIC OR ? HELP and INPUT PLEASE.

Hi everyone,
I was just looking for opinions. Has anybody ever bred a VPI Axanthic to a VPI Axanthic and gotten anything other than a VPI Axanthic. Below in photo number 1 is the sire that was part of producing Axanthic spiders proven.
Number 2 is the Damsel that was produced from the sister to the damsel that produced Axanthic Spiders.
Number 3 is the offspring of the 2 VPI Axanthics but even after several sheds she still looks normal.
Number 4 is just another angle of the same offspring. So what gives? Am I just not seeing she's an axanthic. It was a 3 egg clutch and they all looked like this. Has anyone ever heard of this? Any help would really be appreciated and thank you in advance.

How sure are you that the 2 bred were visual VPI Axanthics? I do a lot of work with them and it's a lot harder to tell as they age because some of them start browning out more than others. Most likely one of the adults is a het and not a visual because the hatchling is definitly not a visual VPI axanthic. Too much yellow and thats exactly what the axanthic gene gets rid of.

Both photo 1 and 2 are the parents.

The first one, or the male parent was purchased as a VPI Axanthic from Dan Sutherland. It was one of his breeders and has produced a lot of axanthics and axanthic spiders for me. He is the only one of the 2 parents that are slightly in question but I am certain he's a VPI axanthic even though he seems browned out a bit. IT'S JUST GOT ME BAFFLED.

The explaination to "number 2" has my head spinning.

It is a bit hard to follow but basically her sister that looks like her produces all axanthics and axanthic spiders. Photo 2 looks unquestionably axanthic right?

I wouldn't say "unquestionably". I have a normal that has a lot less color than her and mine has no axanthic in her at all. That's what I mean, it's pretty easy to tell when they're young but as they age and the colors change it gets a lot harder to tell for sure, unless of course you've had them since hatchlings.
