DNA companies showing up on various TV networks or popular shows and testing the cast has become almost routine. I have seen it on the Steve Harvey Show, Dr. Phil, and a number of other shows and networks. The latest is MyHeritageDNA showing up here: https://blog.myheritage.com/2019/02/myheritage-dna-featured-on-fox-and-friends-2/.
One of the interesting things in this case was the following:
Griff had no preconceived notions about his heritage, and he was very excited to dive in. His ethnic makeup was diverse, and he has close to 15,000 DNA Matches from all over the world!
In most cases, a person has some notion of their heritage. It was nice to see somebody who didn’t.
