What are the "German East" samples on G25 Vahaduo?

[Peterski]

This only really seems to apply to Gotland. The rest of the Viking Age Nordic samples are very much Nordic:

You are using averages not individual samples.

Samples from other islands also have Balto-Slavic individuals, but not as many as in Gotland.

In Gotland the majority, 60%, have Balto-Slavic results, that's why the average looks "Polish".

I promised then but I didn't say that I was going to send the results immediately.

I prefer not to comment on your readiness when it's about doing your part of a data exchange.

fair enough. There must've been some level of crossover during the Viking era leading to Varangians in the east and Balto-Slavic ancestry in the north. For some reason the Vikings didn't leave a genetic imprint on the east.

Finnish themselves have a lot of Baltic shift. It's a mix of Baltic, Nordic, and Uralic.

[rothaer]

(...) So Swedes most likely have Balto-Slavic admixture - just like East Germans. Of course, Swedes have Finnic too.

But that is no cause for me to get SW Finnish in G25 as a somewhat close population. In K36 it's not at all and it seems to be the applicable aspect of the K36 "Fennoscandian" component that lacks representation in all other Eurogenes calculators.
