No, blue borns are not the product of partis, any yorkie can have blue borns.
Peter Coombs book written between 1870 and 1880 states that puppies are often born grey and tan (Which is what today we call blue borns). The gene that produces the grey coat dies and the puppy will lose all its hair. It becomes a hairless dog with only tan which of course carries the living gene to produce this color. This is a blue gene that is a lethal gene. Again it developed in England where it originated from.
