Not sure of the outcome of these:
amel x hypo
creamsicle x hypo

I am going to assume you have an amel corn het. for hypo, and a creamsickle corn het. for hypo. Both are amel because the creamsickle is a corn x emoryi hybrid that is amel. Therefore you will have babies that are all amel. However, they will be carrying emoryi genes from the cream and won't be "pure" corns. They should also exhibit colors somewhere between the adults (between pink/red like the amel corn and yellow/orange like the cream)in varying degrees. As far as the hypo gene, the babies will also be hypo and probable hets for hypo (some will be hypo/ some definite hets/some not het at all). Since all will be amels, you won't see any expression of hypomelanism because the amel genes will take out all black pigment. The babies hypo genes won't come into play until they are bred back to a known "normal" hypo (hypo normal, amber, crimson), or het. hypo "normal" phase where you can see the hypomelanism expressed.

I think I got that right-LOL!!

?????

Assuming none are het for the other trait you will get:

amel x hypo

normals het hypo and amel

Creamsicle x hypo

normals het hypo and amel(creamsicle) these are also called rootbeer corns b/c of the emoryi blood, do not forget that these and all their decendants are NOT pure corn(same with any crossing that involves a non pure corn parent).

If the amel and cream are het hypo then you will get

Amel het hypo x hypo

hypos het amel and normals het amel and hypo

Cream het hypo x hypo

hypos het cream and normals het hypo and amel(cream)

If the hypo is het amel then you will get

amel x hypo het amel

amels het hypo and normals het hypo and amel

Cream x hypo

creams het hypo and normals het hypo and cream

Lastly if the amel and cream are het hypo and the hypo is het amel you will get

Amel het hypo x hypo het amel

amels het hypo, hypos het amel, and i think some hypo amels(sunglows to some)

Cream het hypo x hypo het amel

creams het hypo, hypos het cream, and some hypo creams

in these two crossings the hypo amel or hypo creams will be hard to identify as amel tends to mask hypo.

Hope i helped

Assuming none of your snakes is het for anything, you'll get ALL normals from both pairings.

Creamsicle is an amelanistic cornsnakeXemoryi hybrid/integrade/whatever-ya-wanna-call-it. Ergo, genetics-wise, it's the same as an amel, and thus any crosses to them should be done as if to an amel, except the results should be labeled as not pure corn.

Now, let's assume you breed two of the babies together from one of those pairings... in that clutch, you should get amels, hypos, and normals. Why? Because amelanism masks hypomelanism, so if a snake carries both genes, you won't be able to see the hypo.

I want the Progeny Predictor, but the link doesn't work. Do you have it? Could you e-mail it to me? Thanks!
