In Europe, the frequency of Haplogroup J-M172 drops as one moves northward away from the Mediterranean. In Italy, J-M172 is found with regional frequencies ranging between 9% and 36% (Capelli 2007). In Greece, it is found with regional frequencies ranging between 10% and 48%. Approximately 24% of Turkish men are J-M172 according to a recent study, (Cinnioglu 2004) with regional frequencies ranging between 13% and 40% (Semino 2000). Combined with J-M267, up to half of the Turkish population belongs to Haplogroup J-P209.
It has been proposed that haplogroup subclade J-M410 was linked to populations on ancient Crete by examining the relationship between Anatolian, Cretan, and Greek populations from around early Neolithic sites in Crete. Haplogroup J-M12 was associated with Neolithic Greece (ca. 8500 - 4300 BCE) and was reported to be found in modern Crete (3.1%) and mainland Greece (Macedonia 7.0%, Thessaly 8.8%, Argolis 1.8%) (King 2008).
J-M172 is found at very high frequencies in certain peoples of the Caucasus: among the Ingush 87.4% (Balanovsky 2011), Chechens 55.2% (Balanovsky 2011), Georgians 21%-72%, (Wells 2001), Azeris 24% (Di Giacomo 2004)-48%, (Wells 2001) Abkhaz 25%, (Nasidze 2004) Balkars 24% (Battaglia 2008), Ossetians 24% (Nasidze 2004), Armenians 21% (Wells 2001)-24% (Nasidze 2004), Circassians 21.8% (Balanovsky 2011), and other groups ( Nasidze 2004 and Nasidze 2003).
