no not in a single copied dominate white and a full douple copied. Least I havent seen one yet. You just have to keep up with your breeding records and know what you put in them. Good thing is they either have it or they dont. Not like recessive genes where a single copy isnt expressed visually.
that's pretty much it. Lavnder is one of the recessive genes I was just mentioning in the last post. It must have 2 copies to be seen in the bird. Sex doesnt matter on the breeding works the same either wayI could be very wrong, so take my reply with a grain of salt and wait for someone with much more experience than I have. I have only just started in lavenders myself, but unlike you I have no lavender roosters. I am using black roosters on lavender hens. The sex flip may alter the color outcome, but Im not sure. We'll both be learning from your question I hope!
Anyways.. in my case, I was told that if I use my black rooster over my lavender hens, the chicks will all be black but would carry the lavender gene. Meaning I can cross those chicks to themselves (or other carriers) and get about a quarter which are lavender color, several non lavender but lavender carriers, and the rest blacks with no lavender gene.
This is, however, what I was told on a LangshanX color program. Not a d'anver program. I havent hatched my F1's from the above scenario yet, still about a week to go, so as of now I'm just waiting to see what comes.
