  • Ancestry By DNA results

    Got me results from the ABDNA, and apparently im 100% Euro.. I heard this was so common, so I have to have the Euro 1.0 test..

    Get out the checkbook, here comes the fine print.

      I think there is more detail to be had from the DNATribes offering and ancillary searches of the CODIS markers but look forward to hearing of your results.

        I'm not sure who to believe! The tribes scores seem a bit odd and the DNAP scores do seem generally to be accurate they just don't seem to be able to offer explanations into why those scores might appear! I think both have the science but they don't have the historical/anthropological knowledge.

          Im really confused, then again DNA testing is in its early form.. I should probably go with DNA tribes for more precision marks.. 100% is a little too vague..

            Who to go with?

            Well 100% European isn't specific to me either. If you take the Euro 1.0, I assume you could have 2-4 areas, unless you are 100% of a certain European area (like Northern Europe). If you take the Tribes you get specific countries and regions that you may or may not match too, but no percentages. Depends are what your looking for. Maria

              Yeah, why not check-out Tribes list of populations in their database? Am sure there are some that fit your known ancestry. Such matches would be more informative than just an 'east-west-north-south' Euro 1.0 reading.

                Is the 2.5 test more recent and the Euro test more ancient? Reading different things it seems the 2.5 only goes back 5 generations but the Euro is ancient..anyone know how they worked this out?

                  What?

                  Burto.
                  Where does it say that AncestrybyDNA only goes back 5 generations. That makes a big difference.

                    Well I've seen a few people making references to their scores being because of so and so etc. reading their manual it could be 5 generations back or ancient which I get for the 2.5 test but DNAP are suggesting that the Euro test is ancient?
                    I also noticed that they say that a typical European displays 1.5 East Asian and 3.75 admixture overall as noise...so does that mean for a score of 11% in reality it would be 7.25%?
                    Interesting that they acknowledge that certain Native groups display East Asian instead. They also say that Russians and Eastern Europeans display "a few percent" East Asian....to DNAP 10%+ is "considerable" so according to that this 11% East Asian is higher than a typical Eastern European person..so maybe that can be discounted?

                      I haven't read the website lately but at the beginning they explained that the Ancestry By DNA test only goes back a few generations. It doesn't measure ancestry before that. The percentages work like this:

                      50 percent from each parent
                      25 percent from each grandparent
                      12.5 percent from each great grandparent

                      So if one parent is 100 percent European, you would get 50 percent European on the test. If your other parent is 100 percent Native American you would get 50 percent Native American. But since autosomal is random, you might not get exactly 50 percent from each parent. It's possible to get more or less of something from each one. If you had a great great grandparent that was full blooded something, like Native American for example, it might not even show up on your test at all.

                      From what I remember, very low percentages, like 10 percent or below are not considered accurate. You have to have a grandparent that is full blooded to take it seriously. This formula may have changed since then.

                        By the way, the first time I took the Ancestry By DNA test, I got 5 percent East Asian. I thought one of my parents was East Asian so I had them take the test to see which one but neither of them got any East Asian. So I took the test a second time and this time there was no East Asian. It was all Native American, 60 percent. It's kind of like what happened with the DNA Tribes test. The first time around I got alot of East Asian scores but on the update they disappeared.

                          10% or greater!

                          I was told by the people at ABDNA that you had to have at least 10% or greater of an ethnic group to be considered accurate. It doesn't mean you can't be Native American, if you have less than 10%. This is where they feel comfortable, their cutoff level. Excuse me!

                            Barely made it.

                            Even with all my verified Native American information, I just barely made the 10%.

                              Yeah, that's right. I meant to say below 10 percent. I worded it wrong. And yes, just because that one test doesn't give you a percentage of a specific ancestry doesn't mean you don't have that ancestry. That test is only good for looking at your most recent ancestry, like your grandparents'. I've seen alot of people complain because they don't get a percentage of an ancestry they know they have from their great grandparents. And also, because DNA is so random, it's possible for a more recent ancestry to not show up on the test.
