Patterns of relatedness between IE ethno-linguistic families?

[Peterski]

Would you agree with this graph showing the patterns of relatedness between various IE language families?:



Would the same patterns also apply to ancient genetic relatedness between these IE "meta-ethnicities"?

Daco-Thracian, Illyrian and some other IE families aren't shown, I guess not enough is known about them.

Germanic–Balto-Slavic and Satem (‘Indo-Slavonic’) dialect revisionism by amateur geneticists, or why R1a lineages *must* have spoken Proto-Indo-European

I know it. He has weird theories, he claims that R1a - not N1c - were Finno-Ugric speakers. Which is hilarious considering that for example Finns are basically N1c + I1 without much of R1. I posted several comments on his blog and so far he couldn't debunk my points about N1c. He suggested that N1c expanded into Finno-Ugric speaking R1a areas, without changing the language of areas where it came to.

This guy claimed that entire Corded Ware culture from Norway and Germany to Russia, with all of its R1a, was Finno-Ugric.

As for the topic I can think of a word off the top of my head that is similar in both slavic and germanic which is son/sin. In gaelic it's mac, italian figlio so no connection there for example. as for greek, armenian or albanian dont know the word for son.
