Need help with results

[chiva01]

I am hoping some of you may be able to help me understand my results :) I am getting varied results from the admixture tools... I will post a couple here. I am mostly Irish and Scottish on my dads side and Irish, Dutch and German on my moms side...my grandfather on my moms side always told us his grandmother was Native American...not showing up though. Is my admixture typical of what other Northern Europeans are showing up with? Thanks for looking!!

This is MDLP admixture by chromosome..but it is out of line so it can just give you an idea though. I have some Amerindian showing up here..but I was reading about noise and was not sure how much has to show up before it is not noise

Looks fairly normal for a colonial Euro-American to me, a lot like my mother's results (mainly Isles, the rest Germany/France/Holland). Sometimes these family traditions of NA ancestry are hoaxes, sometimes they get garbled (e.g. his grandmother was _part_ NA which is a lot different), sometimes they are real but the data is hard to read, and sometimes you don't get any genes from an ancestor beyond about 5-6 generations. You might have some traces, though I doubt it because your Arctic-Amerind and South American do not show up at significant levels on the same chromosome:

Arctic-Amerind - - - - - - - 2.8% - - - - - - - 3.0% - 2.0% 1.0% 0.9% - -
South-America_Amerind 1.0% - - - 0.6% - - - 4.0% - - 2.3% - - - 0.5% - - - - 1.0%

That 4.0% could mean something. You may be on to something if you match someone with documented NA ancestry on that spot.

If you can afford to I'd also suggest uploading your results to Family Finder for $69 (http://www.familytreedna.com/products.aspx) to see more matches. The Population Finder is not great but it often picks up Native American ancestry (though it also often shows it as Finnish or Russian).

Thank you for your response! That gives me some insight on what to look for as far as things showing up on the same chromosomes...I just had my mom and dad take tests from FTDNA and they mailed the test back last week so I am waiting on results. Do the chromosomes correlate to generations in any way?

[AJL]

The chromosomes themselves come from a mix of your ancestors and don't really pertain to particular ancestors (except your X and Y).

You have two copies of each of your chromosomes (except males have one X and one Y).

One copy of each chromosome comes from each parent, but they also had two copies from their parents, and they "chop up" their chromosomes when they pass them on to you, so typically your parents will have many matches you don't: these are all still your relatives, just not your genetic relatives.

For this reason it's always best to test the oldest possible relative: half their genetic information is lost in each child. Testing several children can recover most of the genetic matches of a parent, though.

[chiva01]

Thank you...I try to read as much as I can in my free time...problem is I do not really have any..2 kids and now back to school full time! I do not have a paper trail back to Italy, Spain or Portugal ..I have most of my lines going back to the 1700's in the US and then back to the countries I mentioned..Is the high amount of Mediterranean something I should try to look for within the last 5 or 6 generations or is that typical mix in Northern Europeans?

[AJL]

It doesn't seem too unusual and in most cases is probably connected to people from southern Europe settling in more northerly parts of the continent long ago, and those segments persisting in the population. Think of how the Romans were in England, Wales, France, for example.

If you go to GEDmatch and select Eurogenes EUtest model, let it run, then select either 2D or 3D PCA plot.

This will probably give you a better sense of your European ancestry.

Thank you! running it now :)

[chiva01]

Ok Clinton P you are dealing with a serious rookie... I had to run some errands and had to stop looking at it for a bit but back to it now...but what am I supposed to choose for these??Principle Component for X-Axis

[Clinton P]

I would just try different combinations, until it looks right.
Your proximity to the different populations shouldn't change much.
Choosing different Principal Components for each of the axis' changes the perspective essentially.

[chiva01]

I played around with it and the 3d is has a ton of info but is it only showing the populations you match or all populations? there are so many and they are all overtop one another so its kind of hard to look at. I took the Jtest as well
