The results of which stated all the biewers were homozygous for the SINE mutation in the MITF gene promoter. This is the same genotype (SINE/SINE) that has been found in all the other piebald dogs we have tested. 4th International Conference: Advances in canine and feline genomics and inherited diseases

As a member of the BBCA whose members include breeders responsible for importing the first biewers into the US....I have never once been told nor shown any evidence that Mr. Biewer bred anything other than yorkshire terriers. Again if one wants to ascertain where perhaps the piebald gene was introduce into the breed...if one believes that had to happen...doing so is simply conjecture because no one knows. Any conjecture on the german breedings are a moot point regarding the partis that were produced in the US.
The common denominator in both breeds....the line traces back to the same kennel in the United Kingdom and there is evidence to support this. |
The Streamglen line, correct? Has it been established whether or not normally colored yorkshire terriers are also homozygous for the SINE mutation in the MITF gene promoter?
May I ask if any effort is being made by your club to work with the other major biewer club and do what is necessary to become recognized by AKC as Biewer Terriers? Although it failed to pass I would guess that it's just a matter of time before AKC does realign the groups and add more including the Companion Group. They will be looking for breeds to fill the new groups and of course for added income. Why not start to police your ranks, remove those who are using splitters and do what is necessary to become an AKC breed?
The YTCA is trying to NOT open their standard for any reason and they certainly aren't going to open it to add white patches to the accepted colors. They will redo the DQ to make it more specific to the parti color and off colored yorkies. So, parti colors will forever remain the black sheep or should I say spotted sheep of this breed. If the Biewer breeders unite and succeed in becoming recognized it will ensure that there will never be a place for parti color yorkies. Biewers will become the white spotted yorkie type dog shown at AKC shows and you will be considered a legitimate breed.
