I'm trying to put together a little guide of morphs for myself so I can understand this stuff, so I was wondering if anyone could possibly direct me to a site that tells you what the morph is, whether its dom, reccessive, co-dom, what two snakes you have to breed to achieve it, and any information on hets.

I don't quite understand the genetics of snakes. Supposedly, I have a 100% Het Pied male. How do they know its het? If it is 100% Het does this mean they bred two pieds together so it is a sure thing that any normal looking offspring would be 100% Het. What does 66% Het mean? I know there are more % Het but if someone could explain.
