I personally do not care if "partis" are full yorkie or something was mixed in, it makes no difference to me since I will not be using any in my breeding program. If I had one pop up in a litter, just like any incorrectly colored yorkie it would be spayed/neutered before leaving to a pet home. |
You have a good point there. I don't think it looks for those type of genes. And they are indicating that different lines of the same breed contain different markers, so I'm not sure that this testing is really proving what we want to know about the partis and the Biewers.
Also it is only 84% accurate for the first generation and the accuracy rate declines from there.
