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 Hodoğlugil & 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.
