Actually, it's homo for amel and het for anery a.
As for producing something other than snows, take a look at any of the morphs that have either amel or anery in the mix. You could purchase one of those and produce hets and then make more of them in the F2. But in the F1, unless your snake has hidden hets, you can only produce normals, anerys, amels, and snows.
