Autosomal DNA of Trabzon and its districts

Hi everyone. In this week’s article I am going to divide Trabzon in general and Greeks and Turks included in this general average into separate statistics. I am going to share 3 averages based on district, people who are in these district averages come from the same district by all the known ancestry. People who have relatives from two different districts are not included in the district averages, I did not make statistics for some districts due to the few number of people taking autosomal tests but I will update and publish the districts whose number of testees reaches 5. As always, there is the explanation of the components at the end of the statistics. 

To speak of the results,  they in general reflect Anatolian genetics except for the small differences from the peoples I covered in my other articles.

Trabzon general average



Trabzon Turkish average



Trabzon Greek average


Sürmene district average


Çaykara district average


Akçaabat district average


Amerindian - a component, which is modal (i.e has a peak) in various native American groups of North and South America, as well as in ancient DNA of Native Americans (Clovis, Kennewick man, etc).

Ancestor - an archaic component, detected in modern African Pygmy populations (such as Mbuties and Biaka) and Khoisan hunter-gatherers.

Steppe - a component which was sourced from ancient genome of European Bronze Age pastoralists: it roughly approximates levels of ancient North Eurasian hunter-gatherers' heritage, which was subsequently shown to have an influence in later eastern hunter-gatherers and to have spread into Europe via an incursion of Steppe herders beginning 4,500 years ago.

Indian - a component of ancestry harboured by populations of Indian subcontinent

Arctic - a component displayed in genomes of Eskimo Inuits from Greenland and shared with Siberian Chukchis/Koryaks.

Australian - a component of aboriginal ancestry assigned to Australian aborigens.

Caucasian - a major component of ancestry of modern inhabitants of Caucasus, Iran and northern Indian       : it was derived from genomes of mesolithic Caucasian Hunter-gatherers: a major ancestral component linked to CHG was carried west and east by migrating herders from the Eurasian Steppe.

EastAfrican - a very dilluted component being inherited specififically from ancient inhabitants of Ethiopia and African Horn

NorthEastEuropean - a fancy moniker for a dominant type of ancestry in North-Eastern Europe based on older type of ancestry (WHG, west European Hunter-Gatherer), today this type of ancestry peaks in the Baltic region and Scandinavia

NearEast - a component harboured and later carried by ancient populations of Near East, in our time it reaches the maximum among Bedoins and Saudi Arabians; the component seems to carry an excess of Eurasian Basal component relative to Neolithic component.

Neolithic - a component, modeled on genomes of first neolithic farmers of Anatolia (West Asia), these farmers from West Asia migrated to Europe during the Neolithic and carried this component with them.

NorthAfrican - a local component of ancestry found in North Africans: this local North African genetic component is very different from the one found in the populations in the south of the Sahara (Subsaharian component, see below).

Oceanic - a component of aboriginal ancestry assigned to aborigens of Melanesia and Papua-New-Guinea.

Siberian - a component, which is rougly ascribed to Central Siberian (found at highest frequency in Nganasan)

SouthEastAsian - a dominant component of South East Asians: being highest among the Dai, Cambodians, Lahu and Malay, this is the most common East Asian component among South Asians.

Subsaharian - a main component of ancestry seen in Yoruba, Mandenka and Luhya populations.

West, Central and East Trabzon Y-DNA Haplogroups



Having investigated the Y-DNA haplogroups in Trabzon, now I will go into detail by splitting Trabzon into three regions;



Akçaabat, Vakfıkebir, Tonya and Beşikdüzü make up the West Trabzon group.
The Trabzon town, Maçka, Arsin and Araklı make up the Central Trabzon group.
Sürmene, Of, Köprübaşı and Çaykara make up the East Trabzon group.


Let’s begin with West Trabzon;

n:16

G2a: The most dominant haplogroup in West Trabzon, half of the branches in West Trabzon are M406 and the other half are FGC7535. The reason for the increase of the FGC7535 branch here may be that this branch made a founder effect in Tonya, because 80% of the FGC7535 branch found in whole Trabzon are in the Tonya district.

M406

FGC7535 (formerly L293)

You can get information about the other haplogroups from my previous article.


Central Trabzon

n:8

J2a: Most of them are M67 branches.
 


You can get information about the other haplogroups from my previous article.



East Trabzon
  
n:30

East Trabzon is the region where the tested people from Trabzon are most concentrated.



L1b: It is in high frequency in East Trabzon, its most frequent sub-branch is PH8.




G2a: Most of them are M406.

J2a: All of them are M67 and M92 branches.
