If it has little meaning, what's the purpose of it?
Tracing human migrations and sucking money from naive people who want to know answers to question "who am I", especially Americans.
I recommend everyone to avoid especially such services like iGENEA:
https://www.igenea.com/en/home
They are frauds who work in a similar way as fortune-tellers, it's barely legal.
And you better go to a fortune-teller than to iGENEA if you want to know your "origins", because she is much cheaper and her chance to tell you the truth is similar. If you still want to know "who am I", better choose something more reliable than iGENEA, like for example National Geographic's Genographic Project.
But these more reliable services will tell you something like this: "25% West European, 25% East European, 49% unknown European, 1% East Asian". Far less exciting than telling you that you are "30% Alexander the Great, 10% Persian Immortal and 60% Viking", or something like this. Which is what iGENEA does.
=========================
Edit:
I have not ordered such a genetic test for myself, but I can give you results of a guy who shared his results on another forum. Before the test, he researched his genealogy in a usual way, checking ancestors. All his ancestors back to 1830 (as far as he got) were Germans, all with German-sounding surnames. Let's add that his ancestors shortly before emigrating to the USA lived in Western Pomerania, in
Stettin and in several other neighbouring locations.
And here is what the result of his DNA test said:
I. Unassigned - 0,2%
II. European - 99,8%; including:
1. Northern European Groups - 38,6%; including:
a) Scandinavian - 1,2%
b) British & Irish - 0,1%
c) Nonspecific Northern European - 37,3%
2. Eastern European Groups - 19,1%
3. Southern European Groups - 1%; including:
a) Balkan - 0,5%
b) Nonspecific Southern European - 0,5%
4. Ashkenazi Jewish - 0,1%
5. Nonspecific European - 41,1%
IIRC, that was a test which included entire DNA - not only Y-DNA and mtDNA but also autosomal DNA.
==============================
And they also sent him info on how many people from their database have similar DNA to his DNA, and in which countries they live:
Country / number of matches out of total number of people in database from this country / percent of matches:
Matches for 12 Markers checked: 1 exact match and 59 very similar individuals
EXACT MATCH:
Scotland 1 out of 14645 < 0.1 %
GENETIC DISTANCE -1:
Canada 1 out of 452 0.2%
Germany 3 out of 15724 < 0.1 %
Ireland 33 out of 18923 0.2%
Northern Ireland 1 out of 1219 0.1%
Scotland 17 out of 14645 0.1%
United Kingdom 2 out of 12635 < 0.1 %
United States 1 out of 5383 < 0.1 %
Wales 1 out of 2613 < 0.1 %
Matches for 25 Markers checked: none
Matches for 37 Markers checked: none
Matches for 67 Markers checked: none
The more markers are checked, the more detailed is comparison. So he had no "exact clones" anywhere.
