Anatolian Turks

I had some discussions about how the typical Balkan Turk and later how the typical Anatolian Turk would look like. Since the detailed ancestry of most tested Turks is unknown I was looking into other sources and methods. Onur, one of the readers of my blog help me by mentioning:
"Most Dodecad Turks are exclusively from Anatolia, as is clear from the fact that most of them fall in exclusively Anatolian clusters in cluster analyses. BTW, the Behar et al. 2010 Turkish samples are exclusively from the region of Anatolia historically called Cappadocia"
So, I took at the corresponding infromation in the Dodecad project, the ChromoPainter/FineSTRUCTURE analysis of Balkans/West Asia.

The analysis revealed 25 "populations" in the data set (pop0-pop24), two of them are the most interesting for now:
Dienekes wrote:
  • pop10 is Turkish, and includes people with some ancestry from the Balkans, as well as Anatolia. It could be labeled "Balkan Turkish"
  • pop13 is also Turkish, and seems to include people with ancestry exclusively from Anatolia, including almost all the Behar et al. Turks
The great thing is that Dienekes also published the K12b Admixture components of pop10 and pop13. This is can help us to find the best candidate for Anatolian Turks. I also included K12b results of Turks from Hodo─člugil & Mahley (2012).  So, I calculated the TOP30 closest matches for pop10 (Balkan-Anatolian Turkish) and pop13 (Anatolian Turkish).

Top30 matches for pop10 (Balkan-Anatolian Turkish):

 Top30 matches for pop13 (Anatolian Turkish):
Please note that pop10 does not have a lot of good matches, in fact, match#30 (DOD320; adjusted distance: 5.6) of pop13 list is a better match than match#5 (DOD764; adjusted distance: 6.1) of pop10 list. Thus a lot of the lower matches (#14-#30) in pop10 list are not Turks.

The best match for pop10 (Balkan-Anatolian Turkish) of the Dodecad participants is DOD435.
The best match for pop13 (Anatolian Turkish) of the Dodecad participants is DOD433.

Update:

A Top30 list for pop22 was requested.

Dienekes described pop22 as:
  • pop22 could be labeled "Northeastern Anatolia" or (more classically) "Pontus-Colchis". It appears to unite various individuals from Northeastern Turkey and neighboring Georgia, having Karadeniz Turkish, Armenian, Pontic Greek, and Kartvelian ancestry. I strongly encourage participants from this region to join the Project, especially Pontic Greeks, as there are no 100% Pontic Greeks currently in the Project. 
Top30 matches for pop22 (Northeastern Anatolia):

This pop22 is very Armenian (highlighted in yellow), the few non-Armenians in the list are mostly Turkish (highlighted in blue), DOD049 is known to be 1/2 Laz.

The best match for pop22 of the Turkish Dodecad participants is DOD287.

  1. Being the best match for a population cluster does not mean being the best match for that cluster in every component. DOD433 has 4.5% "Siberian", 0% "Southeast Asian" and 4.9% "East Asian" components in K12b analysis, so a total Mongoloid admixture of about 9.4%. OTOH, pop13 (the Anatolian Turkish cluster) has 4.07% "Siberian", 0.02% "Southeast Asian" and 3.29% "East Asian" components in K12b analysis, so a total Mongoloid admixture of about 7.38%, thus 2% less than that of DOD433. The total Mongoloid admixture of pop13 is clearly closer to the total Mongoloid admixture of the Behar Turks (about 6.7% according to K12b), who, as I said before, are exclusively Turks from the Anatolian region that was historically Cappadocia (what is roughly now the Central Anatolian region of Turkey), and to the total Mongoloid admixture of the Hodoglugil Kayseri Turks (about 6.8% according to K12b). BTW, it should be stressed that pop13 excludes the Dodecad Turks from the Anatolian region that was historically Pontus (what is roughly now the eastern Black Sea region of Turkey), as the eastern Black Sea Dodecad Turks are grouped in the pop22 cluster, which almost totally lacks the Mongoloid components. So, pop13 is the average of the Dodecad Turks with exclusively Anatolian (thus no Balkan) Turkish backgrounds excluding the eastern Black Sea region. In short, pop13 excludes the Dodecad Turks with Balkan and/or eastern Black Sea backgrounds. When taking all these facts into consideration, it is clear that DOD433 has more Mongoloid admixture than the average Anatolian Turk, even excluding the eastern Black Sea region.

    When I talked about occasional ethnic and geographical information provided by Dienekes, I was mainly referring to the above two Dodecad threads. Note that for pop10 Dienekes says, "includes people with some ancestry from the Balkans, as well as Anatolia". So it is apparently a Balkan Turk-Anatolian Turk hybrid cluster rather than a full Balkan Turkish cluster. In contrast, pop13 is a full Anatolian Turkish cluster (excluding eastern Black Sea Turks). BTW, Palisto, wish you had made the same TOP30 closest match calculation also for pop22 (the cluster that includes eastern Black Sea Turks).

    1. Also do note that DOD433 is not the best match for pop13, but the best matching Dodecad participant. Indeed, DOD433 is not a particularly close match for pop13, as it is in the 10th position in the TOP30 best match list of pop13. The averages of the Behar Turks and the Hodo─člugil Kayseri and Istanbul Turks are above DOD433 in the TOP30 best match list of pop13.

  2. "Being the best match for a population cluster does not mean being the best match for that cluster in every component. "

    True. Being the best match for a population cluster means being the best match for the sum of all components for that cluster.

    "BTW, Palisto, wish you had made the same TOP30 closest match calculation also for pop22 (the cluster that includes eastern Black Sea Turks)."

    I added it now.

      Yes. And as I stressed in my second post, DOD433 is far from being the best match for pop13.

      I added it now.

      Thanks, Palisto.
