The Author of this map used all Greek FTDNA results and the results from all studies till 2016 to make this map. I1 wasn't sequenced, and the entirety of the I2 is I2a1b-Din/Slav, and the entirety of the R1a is M458, meaning that Z280 is missing, which would've increased the R1a percentage by 2-3%.

I'm sorry, but the idea that the Slavs, who've conquered the largest landmass in the world and exterminated a huge number of non-Slavs along the way, provided maternally mediated admixture in the people they've conquered, is pretty much a wet dream of the defeated. Sure, there are regions where Slavic Y-DNA is slightly lower than the autosomes, but 20-25% Slavic Y-DNA is still a lot, considering there was 0% of it before the 6th and 7th centuries. At this point, you're just applying damage control; you sound like Niggers in the USA going on about "massa's" daughter, even though Massa's been taking turns with your mothers and grandmothers, for generations, whenever he wished.
