Assuming that there are no hidden het genes floating around in the mix, you could expect all of your babies to be motley normals, all of which would be het for amel and anery. If you then bred those babies back together, you could then expect:
1/16 motley - no het
8/16 motley - het for amel, anery, or both
3/16 motley amel - possibly het for anery
3/16 motley anery - possibly het for amel
1/16 motley snow
Of course, those are just the statistical averages. The actual count will likely be different, and if there are any het genes there already (which is very likely), then these percentages will not be representative of the true numbers you'd get.
Also, amel + anery = snow. It's amel + charcoal that gives you blizzards. Have fun!
