Am I correct in assuming that breeding a snow and a hypomelanistic will produce triple hets since the snow is an anery and amel. So the snakes will be het for anery, amel and hypo but will all look like a normal corn. If I breed one of those to a motley would the offspring be a quadruple het? Sorry if these questions seem elementary but genetics is still somewhat confusing to me. Thanks Kevin

The first part is right. The offspring would be normals het amel het anery het hypo.

But, if you bred one of these to a normal motley there would be an approximate 2 in 16 chance of getting a quad het (amel,anery,hypo,motley)

jimmy, why would there be only a 2 in 16 chance? Why don't all the offspring inherit the motley gene? Thanks Kevin

They would. All would be 100% het for motley, 50% het for the other three traits. The 2 in 16 chance that jimmy is talking about is the chance for a single animal to be het for all 4 traits.

So in the first scenario, the breeding of the snow and hypo all offspring would be 100% het because I am breeding the actual morphs, but in scenario two where I breed the motley to the triple hets only a percentage would be quad het because it is a morph to het breeding? Thanks again! Kevin

Thanks for clearing that up, Arlon. That is exactly what I meant.
They would all be het motley but there would only be about a 12 1/2% chance that any of these hatchlings would be quad hets
