>>Emoryi is a subspecies to the corn snake. No this should not change the temperment of the snakes. A cross between a corn and a great plains rat snake sould be called a creamsicle at least the albinos. I'm not to sure on the non albinos. May be someone can help out. I know draybar breeds creamsicles. I hope this helps.

I think Draybar also breeds the cinnamon morph, which I'm trying to do. The cinnamon would be a corn X GP rat cross which is hypomelanistic. I'm using a hypo Miami Phase corn and am going to breed it to a Southern Great Plains Rat.
I don't think you can call these crosses a corn snake any longer, because most folks don't consider the corn and GP rat the same kind of snake. This question has even the experts confused because the debate's been going on for years whether there's one species, two, or even three (slowinskii). Creamsicles have been around for almost as long as amels, but cinnamons are relatively new. There's also crosses that are not morphs. I think most understand the creamsicle is a cross, but breeders need to be up front about selling other crosses/hybrids.
To answer another question, there are many different types of corns and GP rats. Here's a few of the most divergent types: Miami corn, Okeetee corn, Keys ratsnake, Emory's ratsnake, Southern Plains ratsnake (meahllmorum), and the Western Plains rat (intermontana). Some people think these snakes can be very different. The guttatus complex is very involved and getting moreso as time goes on because the GP rats are becoming more popular and more and more locality morphs are being introduced.
I gotta run...off to work...be back tonight. Good luck with that.
