For those of you who do not know what K is - K is the gene that is responsible for the dominant Black in Briards!
Now people can determine if a black (or black born gray) with 2 black parents carries a gene that allows for them to produce tawny puppies.
K is a dominant gene. Dog that are KK or Kk are black.
Only dog that are kk (recessive) are seen as tawny. What type of tawny is decided by other genes.
A KK dog can only produce black puppies. A Kk dog can produce tawny puppies when bred to a tawny or another black that "carries" k.
Testing for briards is available in
HealthGene.
