I absolutely agree, it would a fascinating study to do DNA analysis on more groups of Biewers, Partis, and Yorkshire Terriers to see how they are all related, and to see the differences. Hopefully all the different breed groups can get together and make it happen. There is nothing to fear by doing this work, and it will resolve these questions once and for all. |
Did the introduction of the piebald gene to the yorkie result in the formation of new chromosomes altogether in the Biewer?
If there are chromosomes that are not present in the yorkie, I think that would be reason enough to find the Biewer to be a whole new breed.
