Why DNA Tests Are Unnecessary And Misleading
I’ve had one of these done, but it was to find long-lost relatives, not for the admixture. My mother’s grandfather left her grandmother when my grandfather was very little and died soon after, so we knew almost nothing about him, but through these sites we’ve been able to find relatives from that side of the family who have some information we didn’t. But I do agree that most people really don’t need and misunderstand these sorts of sites.

Raubverleger und Scheinjournale - Wissenschaftliche Publikationen im Zwielicht
