I know this is an old thread, but I just want to comment for future record.
I'm a Biewer breeder and I recently traced my new baby girl's bloodline all the way back to Darling von Friedheck. Together with Fru Fru von Friedheck, the "first" tricolour Yorkie puppies were born to Mr and Mrs Biewer off this pair. The result was caused by a recessive piebald gene.
Through selective breeding in the years to follow, the Biewer breed was cultivated into a sweet, loving companion breed with a very low prey drive. They are totally in tune with their masters and get along well with other dogs and people.
Our dogs are DNA tested to prove that they are different from the Yorkshire Terrier breed. We don't mix with Yorkies or Partis. Partis are often mixed with Yorkies to produce carrier babies, but we'd never cross a Biewer with a Yorkie anymore. It would be considered an outcross of the worst kind (in our club at least). We aim to establish and improve the Biewer breed as a new rare emerging breed.
