Nothing else. The only snakes you can produce with those are normals, anery, hypo, and ghost.
Just get an anery motley. They shouldn't be more than $25-30 at a show. You could even probably get a ghost motley for less than $50. And all of the cornsnakes except for one are recessive morphs. The only known dominant one is the tessera morph.
EDIT:
Also, I am thinking of getting a Motley instead of a Anery. We'll see though because its 25$ for the anery, and like 60$ for the Motley I think. So in the end itll come down to how much money I have at the expo
Also, if I get a Motley, can I produce morphs in the F1 with the Hypo, or does it have to be a regular corn that is Het for Motley?Or will they both achieve the same?
So unless the other snake is het for the trait, you won't produce any visuals in the F1, only hets.
