From what I've read genetic testing has been done to prove that Biewers are there own breed of dog. Right?
And parti yorkies, and this is just a theory, could have resulted from a genetic mutation that resulted in the recessive lighter color gene. Or was the recessive gene always there? Did breeders just breed against this coloration favoring the dominant color we've all come to know? |
One of the biewer breed clubs has elected to mars test their dogs...to try to prove the breed is seperate from yorkshire terriers.
A litter of parti puppies was sired by nikko's rolls royce....the sire and dam were AKC. These dogs were extensively dna'd to prove the parti coloring were indeed the result of a breeding between two standard yorkies. The results of that testing is why they are allowed to be registered AKC. Taking that into consideration the gene had to have been there...
The YTCA club sets the standard for the yorkie coloring. To show in conformation events...the dogs must follow their standard.
