You all of course know that you still will not know what it is you do not know? There is no actual scientific basis for the "results" other than going off of a "presumed" sample - that is directly disputed in the commercials for DNA testing. Simply thinking that X=1 is not pertinent in this dog fight because no one even knows what "1" is!
I have seen DNA testing on dogs where not only is the breed known, six generations of the breed going back over 40 years is known...and the DNA came back as a mini-dachshund (this in a lineage of well bred Golden Retrievers).
The only thing that the DNA purveyors need now is to have Dion Warwick as their spokes person...being as it is Snake Oil and preying on the people who dont know better.
