Yup...that's a hidden gene woma/yellow belly and the breeder male is a hidden gene woma/granite/yellow belly.

As far as Kevin selling 'possible' hidden gene animals, that might be something that would have happened in the first few years of breeding them I would guess...but I am just guessing.

Simply put, Kevin originally thought they looked similar enough to be the same type of animal and after breeding them for years figured out that they were two completely different morphs. In the past I have heard people say that they were sold babies as possible hidden gene animals and not one of them could supply any credible evidence supporting this. Usually it boils down to someone wanting to sell a woma and they tell the buyer that Kevin told them it was a possible hidden gene animal. That makes the animal that much more appealing now doesn't it?
