A focused population profile of Greeks from Kos, their Dodecanese island background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Greeks from Kos come from a Dodecanese island close to Kalymnos and the southwestern Anatolian coast. Kos has ancient Greek, Roman, Byzantine, Ottoman, Italian, and modern Greek historical layers, with strong maritime and island community traditions.
Greek is the main language. Kos should be read as an eastern Aegean island reference, related to Kalymnos, Karpathos, Rhodes, Nisyros, Kastellorizo, Chios, Crete, and other Dodecanese profiles.
As a genetic reference, Greek Dodecanese Kos is useful for comparison with Kalymnos, Karpathos, Chios, east Crete, Nisyros, broad Crete, Ikaria, Rhodes, Kastellorizo, and Santorini.
In the World Genetics modern G25 comparison, the closest non-self match for Greek Dodecanese Kos is Greek Dodecanese Kalymnos. Other nearby references include Greek Dodecanese Karpathos, Greek North Aegean Chios, Greek Crete East, and Greek Dodecanese Nisyros. This gives the Greek Dodecanese Kos profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Kos Greek is best interpreted as a Dodecanese island profile, close to Kalymnos, Karpathos, Chios, east Crete, Nisyros, Rhodes, Kastellorizo, and Santorini.
The heatmap should emphasize Kos, Kalymnos, Karpathos, Chios, Crete, Nisyros, Ikaria, Rhodes, Kastellorizo, Santorini, and the eastern Aegean.
The closest non-self match in this World Genetics comparison is Greek Dodecanese Kalymnos. Other nearby references include Greek Dodecanese Karpathos, Greek North Aegean Chios, Greek Crete East, and Greek Dodecanese Nisyros.
In the current modern G25 reference set, Greek Dodecanese Kalymnos is the closest listed match to the Greek Dodecanese Kos average after removing Greek Dodecanese Kos itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Greek Dodecanese Kos G25 average, giving the closest-match results a geographic view.
