How much ancestry of modern day europeans come from the indo european invaders?

[Pribislav]

That's likely.

Maybe proto Croats and proto Serbs were R1a, and previous Slavs they encountered and conquered in south were I2 ?

If proto-Serbs and proto-Croats were Iranic tribes (there is very popular theory about that) than they probably were predominantly R1a-Z93.

I don't know from Croatians, but among Serbs there is 0% R1a-Z93.
In Serbia only few Hungarians from Vojvodina carry this haplogroup.

Maybe proto-Serbs and proto-Croats were some other branch of R1a.

I think R1a-Z280 more likely
or maybe they already came from north as I2/R1a combination , who knows. Both look to be slavic markers.

Is there a calculator for this?

The calculators on Gedmatch for predicting Indo-European admix are garbage(like MDLP K16). Best method now is using nMonte with R and the Global PCA 25 spreadsheet.

In this map, it shows that South Slavs carry North-Eastern admixture from a North-Eastern incursion, while the natives carry more Atlantic_Mediterranean(WHG+EEF like)


Atlantic_Mediterranean admixture:



This also shuts down the Caucasus theory on Albanians.

Z280 is about 70% of total Serbian R1a, and M458 is about 30%.
What is the relations between Z280 and M458 among Croatians?

According to current knowledge I2a1b2a1 arrived to the Balkans with Slavs.

Depends, i don't know how can the percentage of ancestry that is directly from Yamnaya can be calculated. Yamnaya-related people roamed across Europe. Eastern Hunter Gatherers were in North Europe before Yamnaya culture was ever formed. This EHG ancestry might be the reason North Europeans are seen more PIE-like, geneticwise, bit it's ridicilous. Original Yamnaya people had significant ancestry from CHG and were rather dark. North Europeans have very reduced CHG ancestry as far as i know. South Europeans have more CHG but less EHG. In any case, i think it's rather impossible to calculate.

Absolute majority looks to be Z280 from public databases (unlike one erranous study implied), especially Carpathian-Dalmatian branch.
M458 seems rather rare, with exception of North Adriatic islands Cres and Krk (both have huge percentage of R1a, Cres around 60%, Krk around 40%) which are pred. M458, and it seems to be result of founder effect.

Indeed. The modern ratios are screwed and get inflated/deflated depending on various percentages.

You have to do it urself. Some examples, using relevant samples from the Copper Age and Early Bronze Age. CWC, Bell Beaker and Battle Axe being the Indo-European part. Though you can use Yamnaya aswell, which is maybe more accurate.
Using the same populations for everyone. Including Mozabite + Nganassan for better fit for some Euros.
