The AlabamaMan's new scores:

Southern European: 6.11
Northern European: 62.75
Finnic: 0.25
Balto-Slavic: 4.46
SSA: 0
East Eurasian: 0.49
North Atlantic: 25.94

I'll make a RMSD calculator for this run, but it will have to be tomorrow night. It's almost 2 AM here and I need my beauty sleep.

Would north atlantic be considered celtic? Such as Scotland, Ireland, etc? I'm guessing that symbolizes my half Scottish?

[Polako]

This new run looks quite accurate. For example, my results look close to the Dutch averages!


48.4 "Yellow (North Euro)" (Dutch average 49.88)
19.7 "Red (South Euro)" (Dutch average 10.03)
16.2 "Pink (North Atlantic)" (Dutch average 28.53)
06.3 "Aqua (Baltic or Balto-Slavic)" (Dutch average 8.17)
05.5 "Green (East Euro or Finnic)" (Dutch average 3.17)
02.3 "Blue (Sub-Saharan African)" (Dutch average 0.00)
01.3 "Dark Blue (East Eurasian)" (Dutch average 0.01)

So as can be expected, my Southern Euro is somewhat higher than Dutch presumably because of French Huguenot admixture. North Euro didn't budge, must have been higher to start off with. What gave was North Atlantic, lower than Dutch aves. And, of course, my small non-Euro admixture is present.

Yeah, there was an issue before of your Sub-Saharan admix pushing up the South Euro portion of your genome. But after I added the African samples, that seems to have been resolved. Keep in mind also, that I now have 6 Dutch samples, some from south of the Rhine, as opposed to the two northerners I had previously.

It's pre-Celtic, but yeah, today it certainly peaks in the former Celtic speaking areas of Northwestern Europe, like Ireland and Cornwall.

The southern euro is interesting, I only thought I was 12.5% Italian, what other areas does your southern euro plot cover ?

Well your SE is 17%, not that far off. But SE is not restricted to your Italian ancestry, for example UK averages 4% and France 25%.

If you're 12.5% Italian, then about 60-80% of your Southern European alleles came from that source. I haven't done any averages, but Brits carry about 4% of South Euro on average in this run.

These alleles don't necessarily represent recent Southern European ancestry in Northern and Eastern Europeans, but just allele sharing, because all of Europe was at some point populated from southern Europe. Most of the time they're like geographic coordinates, with South English more likely to carry more of them than North English, etc.

But peaks against people of similar background might reveal patterns in recent ancestry. So, for instance, if a Dane has 7% membership in the South Euro cluster, against the 2-3% of other Danes, then this might indicate admix from south of Denmark. And indeed that is the case in this run, with the Dane who has some German ancestry socring higher South Euro than the other Danes.

My, from this run:

Northern European: 48% (German average: 37%) Highest average: Sweden (59%)
Baltic or Balto-Slavic: 29% (German average: 20%) Highest Average: Lithuanians (85%)
Southern European: 14% (German average: 13%) Highest Average: Greeks (75%)
North Atlantic: 9% (German average: 26%) Highest Average: Ireland (65%)
Eastern European or Finnic: 0% (German average: 5%) Highest Average: North Russian (47%)

My updated results seem to show a higher "East Euro/Finnic" component in comparison to northern Euro, which perhaps explains some Finnic cousins in 23and me

North Atlantic - 77%
E Euro/Finnic - 16%
N. Euro - 6%

Yeah, the 16% is high.

I'm not sure what that means. I suspect that it could be a signal of some really old stuff shared between Northern Europeans in the west and east before the Indo-Europeans expanded from Central Europe into those areas. Otherwise, some sort of Finnic via Norway is an option, but your N Euro is a bit low for that maybe.
