I have yellow labs - 2 groups from 2 different sources. All of the fish from one source have no barring or bearding at all. Almost all of the fish from the other source have barring and bearding.
I'm going to eventually cull the poor ones.
You can have yellow labs that look good, but it is hard to find a really good strain. Any footage of yellow labs in the wild that I have seen - do not have barring, but I don't know for sure if the barring is a natural thing or something that has entered the hobby through hybridization, etc.
What I do know is that mature yellow labs with no barring at all, just great solid yellow, and good dark black on the fins are some of the best looking fish one can keep.
