I am not sure if this reaction to plastic or rubber in the artifical breeding is the cause only could be. I also know my yorkies do not have ressive genes for chocolate. When I first saw the puppies I was both shocked and dumfounded to see the Chocolate color. Why would both puppies born be chocolate unless this is a true mutation caused by something and not passed down? My yorkies do not have any chocolate in their history and not inbred. Inbreeding might cause defects as the chocolate color and many other undiserable traits. If you question my opinions on this being a mutation, please give me some scientific info that I can research. A photo of Misty the female that had the chocolate puppies is attached. She has 9 champions in her pedigree of the Rothby line. She is now 7 years old. wayne |
Does this mean that when a mans condom breaks, there is a possibility of DNA changes in human children
Same principle as Ai, sperm going through a plastic tube. You may be on to something!! Doctors dont know how one acquires Fiber mayalgia(sp?), MS, and a multitude of other auto-immune problems.LOL
As for your pedigree, you have to know every breeder and every dog and what every dog in that pedigree has produced in every litter to find out where your little chocolate ones came from. I dont believe that Roberta Rothenbach has ever produced a chocolate, so I doubt very much if it came from her lines.
