J2f* and J2f1

Cinnioglu et al saw a distribution in Turkey of the sub-groups, J2f* (M67) and J2f1 (M92), that matched well with the territory of a complex society that flourished in NW Anatolia about 4500 years ago. The Maritime Troia Culture "engaged in widespread Aegean trade... involving both the western Anatolian mainland and several of the large islands in the eastern Aegean, Chios, Lemnos and Lesbos". The three earliest layers found in the excavations at Troy are associated with the Maritime Troia Culture. Semino et al agreed that J2f* and J2f1 could have arrived into Europe by way of "sea-faring Neolithic populations who reached southern Italy", or perhaps migrations from Anatolia via the Bosporus Isthmus. Semino et al thought that J2f* and J2f1 could represent, at least partly, the Y component that King and Underhill tied to ceramics in their recent paper. Semino et al estimated the ages of the J2f* and J2f1 subgroups at about 12,000 years and about 9000 years, respectively. These sub-groups (along with J2a and most of the J2*'s) can be distinguished by their alleles at an STR marker called DYS413 (not presently tested by any of the genetic testing companies). For these groups, DYS413a and DYS413b both have alleles of "18" or less (other J's have alleles at DYS413 of greater than "18"). Members of J2f1 may have DYS390=22 more commonly than other members of J (though DYS390=22 is also seen in haplogroups other than J).

Semino saw the greatest frequencies of J2f* in Georgia (13.3%), northern Italy (9.6%), southern Causasus(6.3%), Iraq (4.5%), Greece (4.3%), Spain (3.4%), Turkey(3%), and Albania (3.6%). The distribution of J2f1 seemed to show connections between Anatolia and southern Italy. They saw the sub-group J2f1 in southern Caucasus (6.3%), Greece(3.3%), Turkey (4.4%), Italy (3-7%), and Pakistan/India (4.5%).
