I think this is worth mentioning probably in the history section genetics studies haven t really referred to this much as far as I can tell However we should note that between a third and a quarter of Turkey s population is still a minority even if that is a really high estimate and this probably isn t exclusive descent either as the migrants have intermarried extensively with native Thracian and Anatolian Turks There s the case of the ultimate origin of these migrants and the story there is mixed The Turks of some regions like Crete do in fact seem to be mainly Turkified locals or in some cases Muslim Greeks who still spoke Greek for most of these they re already covered in neighbors With regards to other regions like Bulgaria I ve read things telling a different story of with exception of Pomaks a massive Turkish colonization from densely populated Anatolia i e making the case of migration more like say post French Algeria in a certain sense which would mean these Turkish migrants shared at least some of the ancestry of their Anatolian co ethnics
