So are you saying that they are out cross breeding for the color and inbreeding to purify the breed? upcd
Hi upcd,
No that is not what I am saying upcd. Let me see if you can understand what I am saying by this example or experiment.
Take two clean clear glasses of water and set them on your table. Both are 3/4's full of water and represent pure Birmingham rollers and all the genes that were used to make the breed as we know it.. Now mix them glasses back and fourth. pour one full and the other is half full, almost fill them equally and back and fourth all the genes go in different levels but you still have pure clean water. (Birmingham roller).. No matter how you mix the contents of the glasses, the contents remain clean clear water.
Now you want to cross to another breed for color like the stencil. Get 1 cc of red dye and add it to one glass of the water. Now that glass is no longer clear and clean, it is red, (f1) representing the added genes from the cross breeding. Now pour a little bit of that added to water to the other glass. (f2) Now both birds have changed and are no longer clear and clean. Now mix them glasses back and fourth to any measurement you like. You can't get them to go back to the same gene pool, clean clear water they were before you added the cross to them. So you get another Clean clear glass of water (Pure Birmingham roller) and add the red water into the mix to weaken the pollution. The red gets a little lighter, but it is still changed and not clean and clear and the same as the original glass of water. (Birmingham roller).. It never will be! Especially when you consider, you are breeding birds with the red added together trying to keep the genes you added for the color. No matter how you pour the glasses of water, you never get back to the clean clear glasses of pure Birmingham roller you once had. Trying to keep the cross bred red dye gene pool you added, makes this even more certian. You have polluted the gene pool forever in the Birmingham rollers you are breeding. They will never be the same again. Pour and pour but the polluted gene is passed around. Pour from bird to bird , glass to glass in different levels. The red dye (polluted genes)just mix around in different levels of change. Red dye (cross breeding) has changed what is in the glass. Especially when you consider, you are purposely keeping the glasses with some of the red tent pollution from the other breeds..The breed has changed forever in my opinion, when Mongrelized..
I hope this help you understand cross breeding a little more upcd. I know this is a simple way of looking at it upcd. It should help those that are not deep in genetics get a handle on what cross breeding of breeds means to set breeds. Once changed and the oriental frill or other breeds are added into the mix, the birds you are dealing with, are changed forever.. I hope this helps clear this up for some of you,, Mongrel Lofts

I understand what you are saying, but the chromozomes of living beings are a little different as they are mixed. The matter is correct though; the gene pool is corrupted and the tea is spiked (changed) forever.
We even get some throw backs to the original rock dove now and then in all breeds probably as those chromo's get wrapped around each other.
I like to think I have the real deal, but I cannot be totally sure I do. I have depended on the integrety of breeders gone before me. I do know that I will not mix anything that I know not to be a roller with the families I am working with to eventually get to a point when I can claim them as my own family.
I am one of those that believe the Birmingham Roller to be a specific breed and want to do my small part of trying to keep it that way.
