I find this highly plausible …. my mother fell into that trap of sending in a sample to them. They returned a letter to her and all of her offspring stating we were of rare lineage. They proceeded to hound us to enter studies as we were of only 3% of the world withlikewise DNA. One step further, I was nearly killed in an accident and while in one of the mayo hospitals my family was also houndeed for my blood for DNA studies. They declined.
