I am sure about the boas. One of the breeders I deal with here has the full history. Maybe not albino burms, but the fact is, albinism is an absolute freak gene. It is NOT so common that it can be found as often as you find it today without some serious inbreeding. Luckily, as more people get into hets, it means the bloodlines are starting to outcrop a little more. But unfortunately for most burms, it's too late. They've been inbred for so long, you pretty much can't get one that isn't weakened by the inbreeding.
Nonetheless, this is after MANY generations of inbreeding. And I don't mean 3 or 4. I'm talking in the DOZENS here.
