Y chromosome haplogroups of Kurdish people Part 2:

Today, I want to present Omer Gokcumen's publication. He analyzed the Y-STR values of 4 Central Anatolian villages that are in close proximity to each other, however, they are dominated by different ethnic groups. For some reasons (that I don't want to discuss) he used pseudonyms for the 4 villages, so please do not try to find the locations on a map. One of 4 villages is described as Kurdish, Gokcumen called this villages 'Dogukoy' in his publication.
Based on the figure 6 of the publication (see below), the following Y-STR haplogroups were observed in the Kurdish village of 'Dokukoy': E3b, I1b1, I1b2, J1, J2a, R1a, and R1b in a total of 31 tested individuals from 'Dokukoy'. E1b and J2a are dominating in the Kurdish village, while R1b, R1a, I1b1, I1b2, and J1 are present but relatively low.

A closer look at the Y-STR values of 31 tested individuals from 'Dokukoy' (can be found in the supplementary information) reveals that a lot of cases of J2a are identical or have a very narrow star-like occurence, so maybe Gokcumen et al. just tested a lot of relatives. A even more extreme pattern can be seen in the data set of the village 'Gocmenkoy' (Residents of 'Gocmenkoy' identify themselves with the Afsar clan of the Oguz tribe). Thus, I will not use any of the calculated Y-haplogroup frequencies of this publication, they are misleading. Pictures are sometimes better than 1000 words:
Green, red, blue, and yellow indicate the 'Gocmenkoy', 'Dogukoy', 'Eskikoy', and 'Merkez' settlements, respectively

What can be used from the publication are the variation of observed Y-STR values of the Kurds of 'Dogukoy'.

I will compare these observed Y-STR haplotypes with published data and databases, maybe these 'Kurdish haplotypes' are present in other populations as well. As a starter, just the Modal haplotype for haplogroup J2a in Kurds from 'Dogukoy':


DYS 393 DYS 390 DYS 19 DYS 391 DYS 385a DYS 385b DYS 439 DYS 389I DYS 392 DYS 389II DYS 458 DYS 437 DYS 448 DYS 456 DYS 438 H4 GATA DYS 635
12 23 14 11 13 16 12 12 11 29 16 15 19 15 9 21 22

The closest matches at ysearch are (distance=6/17):
EJ7B6 (Xenofontov, Russia)
6WPPC (Y-DNA J2f-M67 MODAL HAPLOTYPE)
and
G8URM (CruzFajardo, Puerto Rico)
