    Lightbulb Results-Ancestry.com, 97% European ? (picture)

    I have a question concerning test results that someone that I knew got from Ancestry.com. The results they got were this roughly: 97% European (including Irish, British, Scandinavian, Mediterranean, Iberian), 1% Middle Eastern, <1% Caucasian, 1% Unidentified. Does this mean a minority her ancestors came literally from the Middle East/ Caucus mountains ? From I what I can find, there seems to be an inconsistency with taking a genetic test from Ancestry.com vs 23andme and I can't interpret them. Is this Middle Eastern/Caucus DNA being misconstrued as something else, say Slavic ? As far as I know, she doesn't have ancestors on her family tree from that area, but I could be wrong. How many generations would this ancestry go back if it's true? I have included a picture of someone's results that are very similar to the person I know. Here is an example from this article from BusinessInsider:

    http://www.businessinsider.com/best-...cestry-2016-11


    "Here's what the results looked like on an interactive map that they provided. Apart from a trace 1% of DNA from Asia, roughly 99% of my genes suggested European roots, particularly from the Scandinavian countries of Norway and Sweden. By my own rough calculations, I should be 50% Norwegian and at least 37.5% Swedish, so the results weren't super surprising to me."

    "Ancestry lets you look at a more detailed breakdown of your results as well. Here, I noticed something interesting: While AncestryDNA told me I was less than 1% Finnish, 23andMe had estimated that close to 5% of my genes could be traced to Finland. Wanting to know what to make of the difference, I spoke with 23andMe population genetics expert Kasia Bryc, and Cathy Ball, Ancestry's Cathy Ball, vice president of genomics and bioinformatics."

    Thee author of the article got 1% Asian from Ancestry.com, but then she got 100% European from 23andMe. Can someone clear up any confusion here for me ? Thank you.ghael.jpg

    Hi Iphone You will find many comments on this forum about the testing companies and their ethnicity predictions. The consensus is the least worse is 23&me but they are all poor. If your friend downloads her data and uploads to GEDmatch then she can get a better prediction.
    Voodoo with chicken bones was one of the wittier descriptions of these claims! But getting new cousins is good and GEDmatch taking data from all testing companies is best. Welcome to the forum for both you and your friend!

    Hello Judith ! Thank you for your help. Let me ask you a question: do you have any sources that determine why ancestry.com is poor ? i want to learn about this as much as possible. But I haven't been able to find any closure on this, it seems to me that Ancestry.com can sometimes bring random areas into the Map of Ancestry. It's weird honestly. People with Finnish ancestry are often mistaken for having Asian ancestry instead. I know the history of Fenno-Scandanavia is nuanced but it's not Finland is right next to China.

    The chunks <5% appear in a separate section 'Trace regions' and personally I ignore them ;-) Some refer to them as 'noise'.

    What may be more interesting is what if any 'Genetic Communities' she is in, ask her that. These are more detailed and worked out differently. They supposedly represent the more recent past ie hundreds rather than thousands of years.

    Hello MacUalraig ! It's nice to chat with you. I have Scottish in me as well! (his name was Gordon and settled in the USA around 400 years ago.)

    I saw her genetic community, she is apart of the Pennsylvania region and French Canadian group on Ancestry.com. On her map, Pennsylvania was colored red, Quebec was colored orange. Also are you saying that both the 1% Middle Eastern and 1% Caucasian are just noise ?

    Thank you for your help

    I'm saying I wouldn't take much notice or get worked up about wondering how she connects to those areas at 1%. Others may disagree though.

    Oh no, I just wanted to know what "statistical noise" might be in this case. If it's 2% is it actually an ancestor from Caucus Mountains or Middle East? It would be interesting to go to her genealogy. It's the same thing with myself: I might have a Native American ancestor and I wanted to know if that part of my ancestry. would just get dumped in the "statistical noise" category. So, if it does come up I want to be sure that I have it.

    Here is a picture of someone's result on Anthrogenica that are very similar to the person in question, is there some sort of Irish-Central Asian connection ?ghael.jpg

    Also I finnally got ahold of the actual percentages broken down

    Person A
    European 97%
    Ireland 29%
    Europe West 27%
    Scandanavia 15%
    Iberian Penisula 11%
    Europe East 2%

    West Asia 2%
    low confidence region
    Middle East 1%
    Caucasus <1%

    Unidentified 1%
    Thank you for all who help further !

    Hi, there's no short simple way I can think of for explaining why people get these strange small percentages, I suggest just having a read through the forum when you get the chance... just pick a random topic and dig in, I'm afraid that I don't quite know what to suggest for a starting point.
    The individual that got 3% Caucus for example probably doesn't have any ancestral connection to the region.. it just indicates that a small part of their autosomal DNA for whatever reason matched most closely to that population of people in the reference panel. It's a long tunnel which seems to lead to learning about ancient populations and how the modern populations came to be over thousands of years. The different tests don't have the same reference populations and so results vary from test to test, sometimes so much so that the results can be hilarious. I agree with Judith in that 23andme is the best, or... the least bad.

    Best of luck
