To be fair, it's rare to find all 46 chromosomes in any circumstance - especially a touch DNA circumstance. Unless the person recently bled on the object. But often, there's one complete chromosome - which if autosomal, in particular, gives a unique profile.
If several chromosomes are found on an object, unless they are still in the nucleus of the cell, no one can tell for sure that they are all from the same person.
It's not completely clear in this case what exactly is going on with the glove box DNA, as it was explained by lawyers who, IMO, are notorious for bending nomenclature around DNA. Further, sometimes analysis tries to put chromosomes back together if it looks like they should go together, like puzzle pieces (this leads to controversial findings, for sure). What seems to be certain is that more than one Y chromosome was found - but how they would know which autosomal chromosome each of those went with, well...again, unless it was recent and involved body fluid of some kind, it's not easy for a forensic analyst to put a complete picture together. Y chromosome matches are legion (because it doesn't go through a process called "crossover" and so it tends to be passed from father to son virtually unchanged...)
Curious @10ofRods your take on this DNA fiasco. Do you think its smoke and mirrors, just throwing spaghetti at a wall(?) on the part of the defense team?
