"The same dilution gene that causes a black dog to become blue also causes a liver dog to become isabella (aka lilac), which is a pale greyish brown. Dilution and liver are both recessive and relatively rare, so isabella is a rarely seen colour. It is, however, the colour of the Weimaraner, and also occurs occasionally in a handful of other breeds.
An isabella dog will have the genotype bbdd (homozygous for liver, homozygous for dilution)."
I have never seen this color on AKC papers for a Yorkie.....you may have an interesting time trying to get this yorkie registered.....but then I have never had a lilac colored Yorkie! |
