From the HISS Website board....
The little horse genetics discussion and the jungle corn colour discussion going make me wonder if anyone would be interested in a board (forum? I still don't really understand which is which!) about colour genetics in general - we could discuss reptillian and other colour genetics...or maybe just genetic issues in general?
Think anyone else would be interested? Or would it be just me and Ryan?

I'm going to make one now....
Color genetics questions are frequently asked on forums, and this would give those questions a nice little home.
Most of the colubrid color morphs are recessive. But, a lot of boa and python color morphs are co-dominant or incomplete dominant. Some are thought to be polygenic - but it is not all figured out yet and there are a lot of mysteries unravelling every year, especially with ball pythons. It also makes for some really interesting crosses that are easier to do than 2 recessive traits being expressed in homozygous form. (First albino piebald ball python was produced just last year for example)
Ralph Davis is a ball python guy with a few mysteries like this on the go. Last year we had a really cool discussion via email about what might be going on with some of his mysteries, and I presented ideas he had never heard of before, but thought they were really interesting. He thought snake people might be able to learn a thing or two from horse color genetics, after hearing a few of my examples about palominos and cremello's and the agouti modifier that only effects black horses, and has no effect on red horses.
A lot of snake people are not familiar with "lethal white" genes, but there are rumours of some genetics throwing white babies that are born or hatch dead, or die soon afterwards. In some cases, the amount of money involved with some of these python morphs is just crazy, so not all of this information is as free flowing as one would think.
Same for albino boa females. It seems only a fraction of them are able to produce like their normal colored siblings, but it is not openly discussed.
