Slavic admixture in German samples on Global25

[Jana]

In FST sharing Slovenians are closest to Croats, equally close to Bosnians and Slovaks, and closer to Ukrainians than to Czechs.
Croats are closer to Czechs than Slovenes are, and not by a small margin.

[Jana]

If I'm reading this correctly doesn't this say Slovenians are closer to Czechs and Slovaks more than they are to all Southern Slavs but Croats? Heck it says they are even closer to Ukranian.

They are closer to Bosnian muslims than to Czechs. Equally close to Bosnians and Slovaks.
But it is interesting how close they are to Ukrainians.

As I said, southern Slavs are most genetically heterogenous Slavic branch despite small territory they occupy.

Nothing surprising really which would have given Hitler a heart attack, lol. Germans that are living in the eastern part of Germany also had Slavic and Baltic admixtures due to the migrations of Germans to the east and mixing and assimilating the locals to the German fold.

Many of his Brandenburger commandos were Slavs.

Breakdown of Slavic admixture, using only 3 Slavic neighbours in the model
(Slovaks are excluded because they are not direct neighbours of Germany):

Average results for 87 samples (of which some have no eastern admixture):



^^^
As expected, Poles (longest border) and Sorbs (absorbed to the largest degree) make the largest chunks of Slavic admixture:



Model used for that:

Based on those two models, it seems that the breakdown of Slavic admixture in Germans is as follows:

48-45% is Polish-like
31-32% is Sorb-like
21-23% is Czech-like

Question is, if Polabian Slavs such as Obodrites and Veleti, were more like Poles, Sorbs, or like Czechs.

[Peterski]

Plus I think N1c would have been relatively less common in Pruthenians anyway.

If N1c was not common among Prussians then how can we be sure that they were autosomally closer to Lithuanians than Poles?

Some linguists even say that West Balts are not more closely related to East Balts than they are to Slavs.

They say that West Balts formed a 3rd independent branch of Balto-Slavic, equally closely related to both Slavic and East Baltic.

Cool. You've outdone yourself again. I'll share more thoughts after my beer.

Didn't Balts get N1C through bottlenecking? It's not like they are 40% Uralic, they don't have enough East Eurasian admixture for that AFAIK.

If bottlenecking (and associated with it genetic drift) affected East Balts but not West Balts, it could make them also different autosomally as well.

Can my family pass as East German?

That model won't work for Croats. You need to add southern populations to your model. Maybe Bronze Age & Iron Age Croatia and Bulgaria.

French Alsace and Swiss German are absorbing your Med DNA in this model, because they have a good chunk of it (in addition to NW Euro).

Using the code in the original post, I got a pretty good fit.

A good friend of mine had a father from Konigsberg in Prussia and a mother from just north of Oslo.

Per ancestry.com she was:
