I am thinking those numbers are huey. Only because the sample is so small.
Take an albino pyro. has there been any found? Say one has. Then if you look at one mountain range, Say the santa ritas(close to me) There are most likely several million pyros or more there. But only between 100 to 200 are collected a year(at most) That percentage is very low compared to the actual amount in that one mountain range. Then if you factor all the mountian ranges??? Yes, the sample is very low.
Then if you consider the average rate of hatchling failure. Lets say 90%. Then if you factor in that albinos are not naturally suited to survive. Then that lowers what will actually be found compared to how many WERE actually hatched.
With all that said, a geneticsis(sp) fella once told me that het for albinism in snakes in nature was about 1-20. I thought that a little high, but then if you factor all the above in. It very well could be true, Or maybe 1-50 or 1-100. Any of those are pretty close compared to the actual numbers of any species, that is SEEN by humans.
Anyhow, the actual percentage is unknown, as we have very little handle on what population numbers are.
A field herpers, we keep learning that are far more then we thought. And thats with the rare(hides alot) species. Cheers
