  • I took a DNA ancestry test. It didn’t tell me where my ancestors came from…

    At-home DNA ancestry tests have become hugely popular in recent years. More than 26 million have taken one of these tests. If their marketing is to be believed, they can help you learn where your DNA comes from, and even where your ancestors lived.

    But the information that can be inferred from your DNA is actually much more limited than testing companies are letting on. And that has lead consumers to misinterpret their results — which is having negative consequences.

    We did our first collaboration with our friends at Verge Science to explore how at-home DNA tests are putting everyone at risk. Check out their video here: https://youtu.be/7q8Oa97a04g

          It’s still 99.8% right most of the time. So it’s pretty correct.

            It's very important for people to realize that inherited DNA and heritage are not the same thing. Take 6 siblings with the same Mother, and Father, they will have the exact same heritage, but they can have very different inherited DNA. If someone claims to have a certain amount of a certain ancestry, but their DNA shows something different, it doesn't prove them wrong. { Please understand that I am not a political supporter of a certain politician that has had to deal with this problem } We need to stay opened minded about DNA results.

              I guess it's how we all interpreter them. I have always looked at the year to show just how connected we are and what makes us different is the culture we grew up in.

                So remember: just because some shady and inaccurate ancestry test told you that you are 0.1% black even if you are as white as it gets, you're still not allowed to say the n-word.

                        Those DNA test agencies are real covert black operations held by the USA government to gather up different types of specimens for their use...ie, cloning, hybridization, testing, tracking, mind control lol... And whatever else you can think!!

                            Why do you always need to make videos about race at the end? You love dividing people, don’t you? Can’t I just watch a vox video without its politics getting crammed down my throat?

                                            It's actually .1 percent of about 2% of the total dna since only about 2% of our genome produces proteins. DNA really can't tell you anything about ancestry especially antiquitous ancestry.

                                                  Maybe if their on the topic, they should mention the reactions of Middle Eastern / North African Youtubers have when they see Jewish on their results.
