The only way you could get ghost or snows out of your anery would be if he's het for hypo(ghost) or het for amel(snow)...If he's not het for any of these then all you can produce hets...
If you breed your anery to the amel you will get all normals het snow...Breed these hets together and you will get snows...Chances of a snow from these hets are 6.25
If you breed you anery to your snow you will get all anery's het snow...Breed these hets and you will get snows...Chances of a snow from these hets are 25%
To get a ghost corn, you would need to breed your anery to a hypo...This will give you all normals het anery, hypo (ghost)...
Breed these hets and you will get ghosts...Chances of a ghosts from these hets are 6.25%
Sorry so it's so long,
