Hmm, since there were normals and amels, then yours has at least a 2/3rds chance of being het for amel. It is not "for sure" het based on the fact that some siblings were amels.
meaning no matter what i breed my normal with...all that i can get from that clutch is either normals or amels?
Ya, with recessive traits, he can only throw whatever he's het for.
If you are willing to put some time/effort into it, you can figure out what he's het for... and despite what everyone else will tell you, you don't have to buy a female of every corn morph to do it.
He will throw any of his "hets" to about half of his offspring. So, breed him to any cornsnake in the universe. Then keep 3 or more of his daughters, raise them up, and breed them back to him when they're adults.
Whatever he's het for, you can find it when the babies pop out, because there's a good chance one of the females will be among the half of his kids that picked up the same het. The more of his offspring you use to try this, the less likely you are to get a "false negative" result.
