Just for clarification:
Bloodred is a selectively-bred diffused cornsnake. Diffusion is the gene. So when you're referring to the pattern created by diffusion as I believe Susan was, it should be referred to as such while the colored aspect of the morph would be appropriately called a bloodred. I'm not trying to be picky, just feel this is important as the casual use of both had me very confused about what was what for awhile.
