Detecting Small Amerindian Admixture

[Figaro]

I'm no Elizabeth Warren and always felt neutrally about either finding or not finding Amerindian DNA, but I believe my father's mother (who was adopted) could possibly have a branch of her family having a little bit of colonial roots. There are always alternative explanations for Amerindian-like DNA in Europeans (Uralic admixed populations, Turkics, etc), but my father's European roots do not come from areas with activity from those Central asian invaders, nor from F.U.'s.

The only part of my father's 23AndMe which may be "hiding" any possible Amerindian could be his current 0.2% "Japanese"- it is kind of a known thing for that to be a signal of Amerindian DNA. The selection of "Japanese" may be reflecting the possibility that the modern day Japanese, specifically their Jomon component, could have a Siberian origin. There is a possibility my father's small colonial ancestry was from Canada, and I suspect it's a slight bit Inuit, but I have nothing real hard to back that on at the moment...

I see him getting small amounts of hits with Amerindian samples on various Vahaduo tests I have ran his coordinates through. Does anyone recommend some tests or samples that could narrow this down?

To my conviction you can not detect with confidence anything small like 0.2% using G25.

For that purpose 23andMe is already the top of the line.

True, but it is possible that a bit more of that genetic information is "hiding" elsewhere. Anyway, I just got curious about the matter after seeing "Amerindian" signals pop up as I was playing around on Vahaduo. It could be absolutely nothing...perhaps some ANE relics.

YDNA and mtDNA could be such things where indefite small proportions can show up but I guess you've already evaluated that.

At various GEDmatch calculators I get something like 1.7% Siberia which I consider not arbitrary but noise or not correctly labeled. However, in such calculations you get things like that which are far bigger than possibly real 0.2%. So I think all that calculations are simply too rough for such a proportion.

Neither y or mtdna for my father are Amerindian (R1a/H3). By the way, I thumbed up your comment and then accidentally thumbed down right after. Oops. :picard1:

Have you tried the LM Genetics K4 and/or K5 test/s? I have numerous lines that go back to the origins of Europeans in Canada and the US, but that does not equate to a lot of DNA on most Euro-based tests. Try the LM Genetics Global K5 test to see what it gives you (I run it on the Admixture Studio Pro 2.5 platform). You could try running a full 22-chromosome test using that calculator and get your nMonte results at 0.0x distance and add up your pieces of various people groups that will show up.

I'm keen on analyzing some of the chromosome paintings on various GEDmatch tests to see what the Amerindian DNA is typically running with, and it will give you a better feel for what Oceanian-Asian-Siberian-African-India(n) roots might have gotten to you through Native American ancestry. Sadly, there doesn't seem to be a lot of accurate more-recent sample groups from North America to really help us pinpoint all the tribes and times of the little DNA many of us carry. Genealogy is helpful in my case because the French have meticulous records of their people in Canada, but some of my Dad's Mom's lines are tough to filter through in the US because many records were lost in Civil War times, or just not properly recorded and so some lineages hit some brick walls when people moved from state-to-state and record of their birth origin and maiden names were lost.

Start with the LM G. test and see how it goes.

.5% of something completely unrelated to the rest of the data could easily be labeled as noise. If a southeast Asian person scored .5% Celtic/Briton without anything else related to the area it would be noise. Same for the other way around.

The vast majority of my ancestry is NW European, North Sea region to be more precise. I have no gypsy queen or Cherokee princess ancestry nor am I related to the Romanov family 😆. G25 is good for sorting things out because you can use modern individuals instead of generic regional averages. This helps those with atypical ancestry like me. My German is from the north and often shows as Danish while my English usually gets absorbed by my Scotch-Irish. Thus is the North Sea.

Thanks, chief. Of course with these calculators, certain populations are used to describe an “extremity” of the genetics and not describing literal ancestry. Sometimes minor ancestry though can be actual minor ancestry, and so I opened this thread fir second opinions. I myself am thinking it’s ANE noise- I’ve noticed with insular celts they often get such “hits” on G25. Thanks for the words, my fellow countryman.

Try the Dodecad Globe 4 test on DNAgenics site, if possible. I scored 8.43% on that for Amerindian.
