Yes, in order to have anery offspring (since it is a simple recessive mutation) both parents must be at least hets.

The anery babies you produced are 100% het for snow....since a parent is visual albino, they are hets for albino for sure.

The genetics of the normal looking babies is that they are 100% het for albino, and 66% chance of being het for anery (possible double het).

If you breed the anery babies back to EACH OTHER, 1/4 of the offspring will be snows and the other 3/4 will be anerys that are 66% possible het for albino.

Breeding one of the anerys (het ablino) back to your albino mother will produce an equal 4 way split of snows, anerys, albinos, and 100% double hets.

Clear as mud?
Also, this is assuming that all babies in this liter come from the same genetics.
