@see_the_sus They are groupings based on either Y or mitochondrial DNA. They denote branches/forks in a tree of relatedness. The Y branch I'm on is like a twig that developed a few thousand years ago. The mitochondrial group I'm in is more like a main branch that forks off from the trunk of women's inheritance. I will try to find an article that explains it better.
