Why didn't Indo Europeans dominate Scandinavia with R haplogroup?

[Eline]

I heard Finland had the highest IE admixture of all. Very odd that it wouldn't be higher there as well.

proto-Finno-Ugrian people were already EHG people.

Yamnaya was for about 55% EHG. CWC had around the same amount of EHG. So, we cant say for sure that EHG in Fins is from the ancient IEans. EHG in Finns is much older and was in Finno-Ugrian people even before IEans.

Finns don't have much IEan Yamnaya DNA, since they have not that much of IEan CHG. Scandinavian IEans have much more CHG than Finns.

CHG in Europe is the best IEan indicator

They have enough R. Anyway, Indo Europeans weren't pure R anyway.

It just doesn't make much sense to me, as the IE were a very paternal people, who often left women behind as they moved. In most IE societies, prior male populations in new lands were pretty much obliterated, and replaced, which would explain R haplogroup prevalence, and IE admixture overall in modern times, but women don't murder women, so the replacement would never be as deep rooted as it would be if Corded Ware men would have took Scando brides. It doesn't explain how Scandinavia's IE admixture is so high. Unless I'm just missing something here.

Maybe they would live side by side for some time, with one culture having and generating higher amount of offspring through some cultural or biological difference.

Finns don't have high IE as they are mostly HG. They are mostly ydna N1C. Some populations can look like they have inflated IE if you don't use the correct components.

True, they have however a strong CWC input, they lack however EEF similar to Balts unlike Scandinavians who have compared to them slightly higher EEF
So basically Finns are Uralic plus CWC

If there would ever be a place they would do that, it would be a place with a climate as harsh as Scandinavia. Different groups brought different tools to the table for survival.

[Ülev]

what if all those Viking/Norman raids caused R1 dominance? and I1 moved/rescued in Scandinavia?

[Golden Lining]

perhaps they did and for some reason r-people died a lot more because of diseases / later selection and whatever

YUP. Irish have the most

YUP. Irish have the most

This is because Bell Beaker had more CHG for some reasons, while Corded ware was more EHG

[Creoda]

They did dominate Scandinavia. Scandinavians are the most PIE people in the world, alongside Insular Celts. I1 probably came to Scandinavia at the same time as R1b/R1a.
