Northwestern European Populations G25 Results

**Grace O'Malley** · 07-05-2019, 11:56 AM

I'm making this thread because Brittany has been added to the G25 database so because I'm interested in the similarities and differences between Northwestern European populations I'm making this thread.

It is interesting looking at what populations are closest and most distant to each other. I'm just adding the populations first. I'm interested in anyone's opinions on these results.

I'm just going to go up to 500 samples for each. I'm only looking at modern populations averages. Bretons are closer to British, Irish, Dutch, Germans and Scandinavians than they are to other French.

Welsh has only 3 samples which is one of the smallest so it might not be too representative but it is interesting that Brittany is their closest population.

The Breton average (white cross) is surprisingly Northern on the Northern Euro PCA, more so than any of the previous French references and more than many of the Cornish/English. Makes me wonder if I did something wrong or Davidski's sample is not representative.

[1] "distance%=4.4393"

French_Brittany

Yamnaya_Samara,46.4
Barcin_N,38.8
WHG,14.8

Much higher Steppe and lower EEF than the rest of France.

Bretons are closer to British people than to any other French as much as I know. Even on 23andme they mainly get British-Irish.

Is it true that they are mainly descendants of Britons fleeing from the Anglo-Saxons?

This study done on the Western French shows that Bretons share more IBS with Irish than other French. Bretons and Normans are more Northwestern European populations.
