: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.
