I really don't see anything "Yorkie" in the pups except that they are fluffy. They are adorable of course and seem to look a lot like the other with Chi as a puppy.
I know that in some breeds the white gene can be tied to deafness. I have heard that merle can also have some genetic issues tied to it. I hope all of the puppies are only going to be wonderfully loved pets. Can't imagine what kind of human would let a little blind deaf dog be bred!

So glad she was rescued.
