I've been interested in doing this for some time and as the test have become more refined over the years I finally decided to go for it. I chose one sponsored by https://genographic.nationalgeographic.com/as part of a project they're doing on human genetics and migration patterns. The test gives a breakdown by percent on one's racial makeup plus the percentage of Neanderthal genes. Its fine-tuned enough now they can give information on what subgroups you descended from within those races (Northern European, Mediterranean, etc...). I'm pretty excited about it - I hope my background is quite varied (supposedly we have a little Native American ancestry in my family and I'd like to know now much).
Have any of you had this type of testing done? Any considering it? I'm curious if it met your expectations.
