Atlantic Med and North European percentage of Western & Central Turkey

[placebo]

I noticed Central & Western Anatolian Turks scored 25-35 Atlantic Med+North European. Is it because their Turkic heritage is higher than other provinces? (But for example, Giresun or Adana, their East Eurasian is high but Atlantic Med+North Euro is not much high. (20%)) or is it because of the native Anatolians of the region they are mixed? How different between Native Western Anatolians and Native Eastern Anatolians? I don't know much about genetics yet, sorry if this is a silly question.

for example Kocaeli (Northwestern Anatolian province) average

Dodecad K12b:
Gedrosia: 9,61
Siberian: 4,71
Northwest_African: 0
Southeast_Asian: 0,47
Atlantic_Med: 14,32
North_European: 18,8
South_Asian: 2,75
East_African: 0
Southwest_Asian: 10,38
East_Asian: 5,17
Caucasus: 33,78
Sub_Saharan: 0

If you ask the reason why they differ from the Turks from other regions, it is mainly because natives of these regions were having more European admixture than the other regions. Otherwise, regions such as Muğla, Giresun, Mersin would score the highest Euro scores.

Not exactly related to your question but just to help you to imagine input acquired in medieval, we do have samples from Kayseri for both Greeks and Turks, and it can be used while analyzing what Turkic migration brought into the region:

More Eastern Eurasia inheritance should be also more NE inheritance when it comes to the averages. If NE is not reduced after mixing this should point out the native also have a similar amount.

For your other question, we do not have Greek results from Western Anatolia who can be representative of Medieval Greeks of the region. And even if we have got Greek samples from the region, I believe it will be a recent colonizer from the mainland Greece. But according to what we have seen in Turkish results, the native profile of the SW Anatolia should be in the range of Greeks from the Islands, while NW Anatolia is in between Islands and Thrace Greeks -the case in the Kocaeli sample you posted.- Kayseri and Pontic Greeks are pretty useful for Eastern Anatolia, on the other hand.

Atl_Med is not of Turkic origin, its rather native/non-Turkic, North European depends on the region, sometimes non-Turkic+Turkic sometimes mostly Turkic. East Eurasian, North European and Gedrosian admixture were increased by Turkic migration thats sure, but Atl_Med and Caucasus were probably nearly non existent among early Oghuz Turks.
