Character mistake: McCoy asks his witness, an expert geneticist, what the odds are that a DNA sample presented in evidence does not match that of the defendant. He answers "About one in two hundred." That is idiotic. If the DNA samples are identical the chances that the the sample presented in evidence does not come from the defendant is about one in two billion, not one in two hundred! A bright high school senior would know that, never mind an expert geneticist.
Suggested correction: If the odds are 1 in 200, that means the accuracy of the DNA is 99.5%. If the odds are 1 in 2 billion, that means the accuracy of the DNA is 99.9999999995%, which simply isn't true.
In fact as any geneticist (i.e, anyone like me) will tell you the chances of two identical DNA "fingerprints" coming from two different and unrelated individuals are around one in two thousand million. Two billion. In fact the odds are much higher than that but we scientists don't like to make claims that sound unlikely or fantastic. The accuracy of DNA fingerprinting is, as you point out, 99.9999999995%. You correction is wrong and the posting is correct.
Except that's not what happened in the scene or what happens in real life. You simply don't understand what you're arguing. You're not a geneticist.
Blood Money - S10-E8
Character mistake: The coroner claims Reagan was taken to Bethesda Naval Hospital after the assassination attempt. He was taken to George Washington Hospital.
Called Home - S18-E1
Character mistake: Michael Cutter decides to charge Bill Nolan with second-degree manslaughter, and tells Green and Lupo to pick him up. In the next scene, as he and Ed lead Nolan away in cuffs, Lupo says he's under arrest for murder.
Character mistake: In the scene where Serena Southerlyn is speaking to a fingerprint expert, he tells her that he found seven false positives out of the 20 prints tested. Serena replies, "That's almost a third." It's not almost 1/3; it's more than 1/3.
Human Flesh Search Engine - S20-E6
Character mistake: When Bernard reads a line on a website out loud he says "somebody needs to kill him". At the same time we see a close up of the website, which says "somebody should kill him".
Married with Children - S14-E13
Character mistake: The "grandmother" says at first her husband was reluctant to accept the adopted grandchild of the lesbian couple, then says he took one look into those big blue eyes. The child has brown eyes throughout the entire episode.
Benevolence - S3-E22
Character mistake: When the focus of an investigation of the murder of a deaf woman turns from a deaf activist named Paul Crandall, to Gordon Bryce, the hearing director of an institute for the deaf, Ben Stone instructs Mr. Robinette to "tell Crandall's attorney we're dismissing the charges against his client." However, Crandall's attorney, seen earlier in a scene with Stone and Robinette, was actually a woman, played by Camryn Manheim.
