    Default DNA check

    How actuate are these DNA checks? My wife's family is from Honduras, her father who we found about three years ago is from Spain so she really wanted to see where she came from. The results came back yesterday and she is 26% Iberian, 23% Scandinavian, 18% Central American, 11% North African and 22% other with 5% of the total being from Nigeria. I have no idea where the Scandinavian blood came from unless some Viking found his way down to Central America and I'm wondering if we need to celebrate Kwanzaa this year.

    Well, if her father is from Spain, that would explain the scandinavian blood, no?

    That explains the Iberian blood but wouldn't it take someone from Denmark having a wild weekend in Spain for some Scandinavian blood. I want to send one off to a different company and see how close they match up.

    It is possible that her sample was contaminated. But it is also possible that Scandinavians ended up in Honduras or the Iberian peninsula. Plus, how do they come up with those percentages? Do they tell you?

    Turns out that perhaps ancestry checks are not very accurarte:

    I was just looking for a DNA thread the other day.

    My dad signed up for 23andMe and his DNA done. You can connect the results to FamilySearch or Ancestry.com or something like that and it will show you other people who are likely relations based on their DNA profiles. Obviously, it came up with a bunch of people from the Heber valley, which is where he's from. But it also included one random person from Pennsylvania that he didn't know. He doesn't have any family out there or family history in that area. But based on the results, the website said there was a 99% chance they were closely related. The website didn't list the person's name (kind of like linkedin, you could only see connections to a certain degree or something), but the person's husband or something was there. My dad sent a quick email to this person, saying just saying that his DNA profile says they must be related, but he can't figure out how. He didn't get a response.

    Fast forward several months, and my dad was on the phone with his mom up in Heber. There's a bit of an uproar in the family, My dad's uncle's family is going crazy because some woman from Pennsylvania contacted him and said she's his daughter. Turns out the uncle had a child out of wedlock when he was 18 and not yet married, the child was adopted out of state, The uncle got married and had a family, grand kids, etc. and never told anyone, not even his wife about the kid. Now his 80-something-year old wife and their kids are pissed at him because he has a kid they never told him about. No one knows that my dad basically stated it all with his DNA profile.
    Ain't it like most people, I'm no different. We love to talk on things we don't know about.

    Why couldn't someone from Scandinavia just move to Spain, marry a spanish person, and have kids? There's certainly no lack of that sort of thing happening in the U.S. (I'm looking at you, Swenson!)

    Interesting story. Be careful what you ask for, I guess. Just as a note, however, the connection at the base of your story is very difference from the sort of cultural/ethnic background conclusion given to RC's wife. Easy to see that any two individuals must be closely related. Much more difficult to say your background is some percentage of some ethnic group.

    Historically Scandinavian DNA was sprinkled liberally, if you know what I mean, all over coastal communities of Europe.

    Yeah, I get the difference. I just wanted to share the story.

    My FIL had his DNA checked a while back. He's as white and as English as they come. Except for the fact that the test said he had a certain percentage of Caribbean blood. Now he says he's part black.

    I have a good chuck of Iberian DNA as well. No known ancestors there. Lots of my ancestry goes back through England, but my DNA is only 10% English. I do have a darker skin tone, so the Iberian makes a little sense.

    When my dad first did the DNA test several years ago, it had some origins in Italy (Europe South), but that later moved to the Iberian peninsula. So they are definitely refining the results.

    Here's my breakdown:

    Ireland/Scotland/Wales 40%
    Scandinavia 21%
    Iberian Peninsula 17%
    Great Britain 10%
    Europe East 6%

    I also thought I'd have more German ancestry because my grandmother has a German maiden name. My Europe West is only 4% (low confidence).

    The biggest revelation is that I fall under the "Mountain West Mormon Pioneers" "Migration".

    Interestingly, I have Portuguese listed on my birth certificate. My grandmother's maiden name is Coelho. And I have less than 1% Iberian.

    My parents purchased tests for all my siblings for Christmas. I'm curious to see how we differ.

    Here is my sister's results, which I assume would be close to mine as well. My mom won't take the test, but she was born and raised in Sweden with all her ancestors in Sweden as far as we know. My dad, who is American, scored 40% Scandinavian as well, so it seems weird that combined with my born and raised Swede mother, it only came back with 43%

    43% Scandinavia
    31% Europe West
    10% Finland/Northwest Russia
    9% Ireland
    3% Iberian Peninsula
    2% Italy/Greece
    2% Great Britain
    <1% Europe East

    Mine was very close to what expected. The biggest shock was that I had more Irish than expected and less Scottish. My wife way very different from her family lore. The family story was that her great great grandfather was a monk from Turkey that came to the Philippines and started a family. Her DNA test showed she was something like 65% SE Asia and 35% Polynesia.

    My mom is super old and hates all things that interfere with her privacy. She has never been on the internet (nor has she ever touched a computer of any kind), she hates to fly and refuses to go in that new scanner that basically looks through your clothes. She is stubborn as can be and would never giver her DNA to big brother.

    Or it might be what you guys are thinking. Who knows.

    The most surprising thing for me with this was that my grandpa who had a very Italian last name who I always thought had a lot of Italian heritage was I guess barely Italian at all.

    Doesn't surprise me at all that an "Iberian" would turn out to be high Scandinavian.

    One of the very touchy things genetic counselors have to deal with all the time when a family comes in to figure out what's going on with their child and his genetic illness is that paternity is not what men have been led to believe. There is a lot more cuckoldry going on than most people realize.

    But thatís a different sort of comparison. Itís easy to establish whether any two individuals are related, especially as a parent and child. But it is not nearly as reliable to establish ethnic/cultural heritage.

    Sure but I'm gonna go out on a limb and say these DNA tests are a helluva lot more accurate than most people's vague assumptions about their ancestry.

    Probably. Except it would be a mistake to assume grandma has been lying about her background just because the test says she has some percentage of Scandinavian genes or some such. Itís more like a parlor game than anything to rely on.

    They're definitely continually refining the results. I know they try to find small villages around the world where the people have been fairly isolated from outside dna for about 5 generations to get a better picture of dna typical to that area. But then another village 50 miles away might demonstrate very different results.

    I took an AncestryDNA test a number of years ago, and it came back as 49% Central European and 44% Scandinavian. A couple of years later the ethnicity estimate of that same test showed 68% Europe West, 12% Great Britain, and 9% Ireland/Scotland/Wales. I was in an early test of another ethnicity estimate recently, and it showed 68% Britain/Northern Europe, 22% Ireland/Scotland/Wales, and 7% Germanic Europe. My grandmother was born in Bavaria, and you'd think it would show 25% German, so every ethnicity model has its faults.

    But my brother took a test, and it identified us as brothers, and a couple of 1st cousins have taken tests, and they were listed as likely 1st or 2nd cousins.

    As for the genetic communities such as the Mormon Pioneer Migration, yeah, that's obvious to you, but there are quite a few communities being identified that people are not as familiar with, especially for those who don't have a 4+-generation pedigree chart.

    I did Ancestry.com and it was $100 or so. I don't remember the exact percentages, but I'm around 40/40/20 Western European/Scandanavian/British Isles. I assumed that the Western European comes from the Normans as my lineage all comes from the British Isles and Sweden with pretty solid documentation, but we all know there were plenty of love children in the world.

    If the messaging of consumer DNA companies more accurately reflected the science, though, it might be a lot less compelling: Spit in a tube and find out where on the planet it’s statistically probable that you share ancestry with today.
