Yes, you read that right. Explore your own DNA at home by using liquid soap, salt and vodka. Oh yes, you will also need some saliva.
Disclaimer: I am not recommending this “test” as a suitable substitute for DNA testing by one of the laboratories that specialize in DNA analysis. However, it is an interesting story so I will repeat it here. After reading this, you are on your own!
One other problem: while you can extract your own DNA from your saliva sample, Dr Brian Cox does not describe how to examine the DNA to determine your ethnic heritage. Maybe that will be in the follow-on video. Then again, maybe not.
As for me, I think I will save the vodka for other purposes…
