    One set of identical twins, two different ancestry profiles.

    At least that's the suggestion from one of the world's largest ancestry DNA testing companies.

    Last spring, Marketplace host Charlsie Agro and her twin sister, Carly, bought home kits from AncestryDNA, MyHeritage, 23andMe, FamilyTreeDNA and Living DNA, and mailed samples of their DNA to each company for analysis.

    Despite having virtually identical DNA, the twins did not receive matching results from any of the companies.

    In most cases, the results from the same company traced each sister's ancestry to the same parts of the world — albeit by varying percentages.

    But the results from California-based 23andMe seemed to suggest each twin had unique twists in their ancestry composition.

    Surprise, surprise ... Not!

    Lack of oversight

    The biggest DNA ancestry companies have tested millions of people. MyHeritage, for example, says it expects sales of well over $100 million this year.

    Despite the popularity of ancestry testing, there is absolutely no government or professional oversight of the industry to ensure the validity of the results.

    It's a situation Gravel finds troubling.

    "Usually in science we have a process like peer review and make the data accessible, and make the algorithms accessible, that's how we ensure the high quality of the data," he said.

    "In this case, we don't have access to that because the companies keep the data private."

    My mom, sister and sister's kids did 23 and Me. I was not willing to participate because I think that these companies are just fronts and they are obtaining our DNA to put it into a database for the government. They laughed at me and told me I was paranoid, but I think they are way too trusting. Really, though, I was protecting my mom. I have red hair. Neither of my parents do, but our milkman did in Indianapolis, where I was conceived and born. LOL. It was quite the joke in our neighborhood, I guess, until my red-haired grandma came to visit.

    Anyways, the results pretty much matched family memories and records, but there were some weird things. My younger niece had both Neanderthal and Native American DNA in trace levels. My sister had mostly Western European DNA, and my mom had a mixture of Western and Eastern European DNA.

    The Native American probably comes through my BIL's French-Canadian family ties, but my dad also has similar ties. I even looked up some family records and one of my dad's ancestors, who worked as a guide for Hudson Bay Company, had a Native American wife. I'm just not sure if we descended from her, or if there was a previous or later wife of WASP descent.

    Noonie~

    Enjoyed your post.

    Who cares what DNA ancestry did or didn't make you what you are today ...

    You come across as a very nice caring person, especially with what you do dealing with troubled children.

    In fact, if only you were a "Conservative" ...

    You would almost be perfect!

    Here is something these DNA testing kit company's don't tell everyone.

    They don't work very well on women.

    Reason is because of the XX and XY chromosomes.

    Because testing companies can't deference between the XX as easily as the XY, (You get the X from your mother, and the Y from your father) they can only really do the maternal side of the family. SO women doing these test, don't get their paternal sides.

    Genuinely curious, do you have any documentation on that? Do males doing the tests get both sides or just maternal? I've done an Ancestry.com one, but if all it got was Mom's side, that leaves a lot open, because Dad was adopted.

    Noonie, i too wonder about who all has access to those databases and the possible use/abuse of the information. Mom has been doing genealogy for several years, ordered the tests, but my brother wouldn't take it for similar reasons to yours, I said what the heck and used his, despite some mild paranoia.

    ABC, no, DNA doesn't make you who you are today, but it is interesting to see one's own history. There's also an argument to look for medical interests, see if there are things that need to be watched. However.....

    “If you’re a woman it’s worth asking your brother “ some times that works and sometimes not. Not every child of a couple will produce the same results even if two brothers or two sisters. My family is proof. Two daughters with different dna results.
    It's not how old you are, it's how you got here.

    I should have worded that better. What I meant was no matter what those money-making-tests showed her true or not-so-true ancestral DNA to be ...

    Noonie herself, and her 23 pairs of chromosomes, from whomever they came ...

    Turned out very well.

    'Tis all I was getting at.
