I've always wondered,I suppose this thread is as good of place as any to look for an answer....if you receive whole blood from another person,do you now share the persons DNA??

No. The cells in transfused blood don't reproduce, but slowly die off and are replaced by one's own blood as the blood-cell producing cells in your bone marrow (and elsewhere) operate on their normal cycle.

If a DNA profile was performed on your blood soon after you had received a transfusion, there'd be some confusion, as both profiles would be mixed together. But after a few weeks, the transfused cells would be gone.
