I could follow if I knew what the terms mean. Weird names I don’t follow , imperial, native.
So all the yaks here are inbred with cattle?
no not many BUT IYAK want's to keep it that way. The white yaks in the US ALL have cattle gene's mainly Charolis which is where the white color came from originally. Some breeders are doing LOTS of line breeding to up the YAK % to get them into the considered full blooded yak again.
