I think the problem with the Albino's is that the amount of inbreeding that is needed to be done to produce the quantities that are out there in such a short amount of time. I did give a senario but it seems to have been removed as it was caught in another debate.It has never been the case in NSW.
But doing the math on what we know it would not be hard to imagine that genetic defects along with the albino mutation would be getting re enforced. As for the hets it is no surprise as most of the breeders would have started out with one albino resulting in more inbreeding within one clutch. . . even though it can be argued that the additional initial new non albino would be adding genetic diversity.
