The genetics of bp morphs is totally unknown to me, is there a table anywhere giving the inheritance of each (dominant, recessive, co-dominant etc)? I can't seem top find one in teh FAQs.

The man in the shop showed me some very special pythons, gorgeous lemon pastel hatchlings, adult cinnamon pastel and piebald (the latter two are nearly getting into deposit on new flat territory (outside London that is!), terrifying price tags!).
