Additionally to Heather's answer
I know with the ivory morph that yellow bellies (normals with yellow bellies?) show the recessive gene, and I know some corn snakes can show recessive genes, but does the Piebald gene show out?
YB are not normals they are a morph in their own right maybe a little more subtle but still a morph, which is co-dominant and not recessive.
Along with any and all info on pies, the two leucistic morphs, and ivories, that about covers it. I'm also curious about prices for most common morphs (normals, pastels, super pastels, mojaves, super mojaves(?)), the pies, both lucies, and ivory BPs. I can't even guess the prices on these guys except for normals and plain ol' pastels. X_X
go on kingsnake and this will give you a general idea on pricing
