Perhaps he’s late to the party, but PG immediately thought about the literary possibilities of this technology in the hands of some fiction authors.

I can’t see the video at the moment (I’m assuming there is one; there’s a giant amount of space otherwise).
There are so many twists and turns to take with DNA, though! What if the person is a chimera? Chimerism is the opposite of twinning, where instead of separating, two are merged together. “Law & Order” used that notion, where a man had the DNA of his fraternal twin brother in one part of his body, and his own DNA in a different part. I think the detectives figured it out because he gave hair or saliva samples in one instance, then a blood sample in another instance.
Yes, it’s a great tool. About six years ago I used DNA as a proof of paternity plot device in a dysfunctional family novella called Enigma. The story was set in 2009, just as DNA testing was getting up and running outside the boundaries of law enforcement and academia.
