On the Snow/Normal same clutch issue:
Depends what the parents were. If one of the parents was a snow and the other het for Amel and Anery then yes, the normal would be 100% double het.
If One parent was Amel het Anery and the other Anery het Amel, then yes your normal would be 100% double het.
However, there is also the possibility both parent were Amel het Anery or both were Anery het Amel in which case you are looking at 100% het for one and 66% poss het for the other.
Or, both parents could have been double hets which would make your normal 66% poss double het.
So in a nutshell, you will have to breed the normal to something with Amel and something with Anery to find out for sure.
