Do Modern Greeks genetically related to Ancient greeks?

Do modern Greeks share at least some genetic ancestry with ancient Greeks, or they are totally Turkic/Semitic by blood? There are two international, intercollegiate genetic researches published in 2017, with over 20 universities and institutions involved, which prove beyond any doubt that modern Greeks, from the mainland, the islands, and the Greek immigrants from Anatolia, who were expelled from modern Turkey to Greece in 1923, are direct descendants from the ancient Greeks and furthermore the direct descendants of the neolithic populations living in those areas (known as Pre-Greeks, or Pelasgians). The continuity is striking since it ranges from 80% to 93%. Another striking fact is that the Greeks in general are not at all related to the Turks, a minimal relation of 2% is present only in some particular populations originating from specific areas of Asia Minor. Also, let me point out to you that Modern Greeks speak a modern version of the Greek language, write with the same alphabet used for over 2,600 years, and still use a lot of their ancient customs and habits. Therefore, they are also closely related to the ancients culturally and linguistically.
