Dr. Anne Crowley: You have a very rare chromosomal pattern, Mr. Ball. You are, more specifically, one in two billion. Were you aware you are from the Huntsville subgroup?
Kevin Ball: What the hell is that?
Dr. Anne Crowley: It's a genetic signature that only comes from one very particular area in Kentucky. They were cut off from civilization by the Johnsville flood in 1826. Trapped in a rural area known as a "hollar," until someone found them again 120 years later. As a result, they are one of the most inbred populations in the United States.
Veronica Fisher: Did you say "inbred"?
Kevin Ball: Did you say "Kentucky"?
