Revisiting Kurdish autosomal DNA

Update: 19.09.2014

I thought I should merge all samples of KurdishDNA and this blog and try to shed some light on. Here's the total of 34 samples.

Ezidi: 2
Feyli: 3
Kurmanji: 15
Sorani: 10
Zazaki: 9
of samples

First all major subgroups' ADMIXTURE values from Dodecad K12b calculator.(Population Averages)


There is not much of difference between sub-groups other than expected gradual variation by the geography. Feylis score the highest Gedrosia+pseudo South Asian+lowest Mediterranean and Zazaki's highest Caucasus+lowest pseudo South Asian, Kurmanjis similar to Zazakis additionally have highest Atlantic-Mediterrean and North European components.



Distances between dialect and religious sub-groups

Kurds_F Kurds_S Kurds_E Kurds_K Kurds_Z
Kurds_F 0 2,809 2,243 5,920 6,047
Kurds_S 2,809 0 2,665 5,109 5,540
Kurds_E 2,243 2,665 0 5,788 6,250
Kurds_K 5,920 5,109 5,788 0 1,519
Kurds_Z 6,047 5,540 6,250 1,519 0

There appears to be only 3 sub-groups when all samples are considered(n=34),  #2 is a Kurdish exclave:
#1 Northern/Western (Kurmanji, Zazaki)
#2 Central Anatolian Kurds (Kurdên Anatoliya Navîn)
#3 Southern/Eastern (Ezidi, Sorani, Feyli)
(see Results by class: )

Reminder this North/South divide is more pronounced because of the sample bias. See my previous post about Participants Map, most northern samples are from Dersim and most southern samples are from Silêmanî. If there were more samples between those areas gradual difference would be much more finer.

Participants Map


I've received a few values from Palisto and thought it would be better with using a map with all samples.

E: Ezidi
F: Feyli
K: Kurmanji
S: Sorani
Z: Zazaki
