Just to fully explain things.
Most cornsnake morphs are caused be recessive genes. Amel, short for amelanistic is a recessive gene that removes all the black pigment in a cornsnake. Amelanistic means no melanin, which is the black pigment
Anery is a recessive gene that eliminates the red pigement, erythrin is the red pigmentation so anerythristic means no erythrin
Hypo-melanistic reduces the black but does not eliminate it totally
Caramel turns the red pigment to yellow pigment (Xanthin)
There are about two dozen known recessive genes that cause visual morphs.
What would properly be called Creamsicle has the amelanistic morph as well as a percentage of emory's rat snake genes. Emory is probably the closest related snake to a corn snake, it used to be considered a sub species of corn, I don't think it is anymore.
An emory's looks very close to anery corn snake, very low red colour. Mixing it with corn snake gives you something that looks almost like a pure corn snake but with reduced red colour, we call this a rootbeer. Mix in the amel gene and take away the black pigment and you get a creamsicle, the red is reduced and looks more orange.
A picture or two would be nice, sometimes pets stores or people selling the snakes don't understand that these names have genetic meanings and think they only describe colour. There are orange amels that are pure corns, there are emory's hybrids that have intense red. It's always good to get a second opinion from us corn snake nerds.
