West Pomeranian Voivodeship = Mixed population after WW2

Lower Silesian Voivodeship = Mixed population after WW2

Lubusz Voivodeship = Mixed population after WW2

[Peterski]

Southwestern, South-Central, West-Central and Western Poles are most similar to Slovaks (and Moravians). In Pomerania Kashubs are most similar to Belarusians while Poles (from Kociewie region) to Slovaks. Masurians (from Warmia-Masuria) and Masovians are most similar to Belarusians, as well as people from Podlachia (here also high similarity to Lithuanians around Suwalki). People from Lublin Voivodeship, Subcarpathian and from Holy Cross Voivodeships are most similar to Ukrainians.

[Peterski]

Now with Sorbs taken into account:

[Peterski]

West-Central, Western and Northwestern Poles are most similar to Sorbs (a small Slavic ethnic group from Saxony and Brandenburg in Germany). Polish Silesians are most similar to Sorbs and to Slovaks. South-Central Poles (Lesser Poland Voivodeship) are most similar to Slovaks. Masovians are most similar to Belarusians, as well as people from Podlachia (here around Suwalki also high similarity to Lithuanians). People from Lublin Voivodeship, Subcarpathian Voivodeship, Holy Cross Voivodeship and from Radom region are most similar to Ukrainians.

[Vessna]

23andMe lists the Podlachia region as my close genetic group.

[Valenman]

It's interesting to know if a Slovak would have a German great-grandfather.
Is he genetically similar to a some sort of Pseudo-Western/Central Polish?

[cass]

It's interesting to know if a Slovak would have a German great-grandfather.
Is he genetically similar to a some sort of Pseudo-Western/Central Polish?

Yes, but only at first glance. In a model that includes the Balkan component, the Slovak or Czech will always stand out.

23andMe lists the Podlachia region as my close genetic group.

Podlachian Poles are to a quite large degree descended from Polonized Belarusians, so it makes sense.

[ScandinavianCelt]

This is what my closest Polish sample gets on the sim-map: (Silesian 2)

https://i.postimg.cc/LshdKmCF/silesian2-simmap.png (https://postimages.org/)

I often get Polish21 as well on calcs, and it's primarily Ukrainian with some SW Hungarian on the sim-map.
