Your amel motley het caramel is the only snake that figures somewhere into a blizzard mix...Without just starting off with a blizzard, and factoring out the caramel for now, I'd go with a charcoal thats at least het for one of the pattern morphs, either motley, stripe or mot/stripe...For the sake of argument you decide on a charcoal motley and breed it to the amel...Your first generation babies will be motleys het amel and charcoal (blizzard) possibly also het (a 50% chance for each baby) caramel...You could then breed them together to get motleys, amel motleys, charcoal motleys and/or blizzard motleys...with a possibility of getting the caramel gene back into the mix if some of the first generation turn up positively het for caramel...Takes a few years but it'd be a fun project :*)
