Online genetics calculator question - clearnecked????

[Cloverleaf Farm]

Ok, genetics gurus, I have a question for you. I am working on a mille fleur project, and am doing some double checking with the online genetics calculator. Some of the offspring say "clearnecked" and some don't. The not so detailed pictures look exactly the same. I see the difference in the loci, but without knowing what each individual one does, I don't know what I'm looking for visually in the offspring to know which patterned birds to keep and which to cull. The ones that don't say "clearnecked" are the ones with the correct loci for the mille fleur pattern. ???????????????

Thanks!!

The Db gene removes black pattern from the neck hence clearnecked.
Millefleur should be on Co/Co though. Heavy hackle striping can be selected against.
Or use wheaten (E^Wh) instead of brown (e^b)
