What other type of chromosomes must be ID'd?? Do they even know or is it a random search to find like chromosomes that are different from the Yorkies??

To me it would be beneficial to run another set of DNA tests on the Biewers, Parti's and possibly the Yorkies to research the likes and differences of the 3 breeds. |
Biewers by definition have the white color patches caused by the piebald gene, so that part is taken care of. When MARS created their breed test for the Biewer, they used DNA markers on most, if not all, of the dog chromosomes. Some chromosome segments in the group of 100 Biewers were more like Yorkshire Terrier chromosomes, other chromosome segments were more like other breeds--it was an interesting data set. So yes, they do know which chromosomes are different.
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.
