No. They aren't even always compatible within the same species or even subspecies.

For example - amel in cal kings does happen to be compat with amel in corns but if I recall correctly is NOT compat with amel in their closer relative, the desert kingsnake.

There are several lavender genes in cal king that are difficult if not impossible to tell apart visually that are not compat - pair them up and you get normals that are double het - and who knows which (if any) of the cal king lavender genes are compat with what genes in corn snakes.

I believe the amel gene in Emoryi ratsnakes is not compat w/ amel in corn. The creamsicle I believe usually uses the corn snake amel gene, but I suppose you could make a line of creamsicle that uses the Emoryi amel gene. I wonder if it would look different.
