Correction: If the amel male was het for anery, when bred to your snows, you would get amels and snows...no anerys. You would need to breed the snows to an anery to get anery offspring. The only other possibilities would be if they were het for any other genes, but to determine that, they would need to be bred to a snake known to carry those other genes, but if they aren't het for anything else, you will only normals with hets.
