A focused population profile of Greeks from Kastellorizo, their far eastern Dodecanese background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Greeks from Kastellorizo come from a small island at the far eastern edge of the Dodecanese, near the southern Anatolian coast. Kastellorizo has a history of maritime trade, Greek island communities, Ottoman and Italian periods, wartime displacement, and large diaspora communities in Australia and elsewhere.
Greek is the main language. Because this reference has a small sample size and comes from a very specific island, it should be compared carefully with Symi, Rhodes, Karpathos, Greek Cyprus, Kos, Kalymnos, Lycaonia/Ikonio Greeks, Turkish Cyprus, and Chios.
As a genetic reference, Greek Dodecanese Kastellorizo is useful for comparison with Symi, Rhodes, Karpathos, Greek Cyprus, Kos, Kalymnos, Greek Lycaonia Ikonio, Nisyros, Turkish Cyprus, and Chios.
In the World Genetics modern G25 comparison, Greek Dodecanese Kastellorizo is closest to Greek Dodecanese Symi, Greek Dodecanese Rhodes, Greek Dodecanese Karpathos, Greek Cyprus, Greek Dodecanese Kos, Greek Dodecanese Kalymnos, Greek Lycaonia Ikonio, Greek Dodecanese Nisyros, Turkish Cyprus, and Greek North Aegean Chios. The result places Kastellorizo in a far eastern Aegean and Cyprus/Anatolian-adjacent island cluster.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Kastellorizo Greek is best interpreted as a far eastern Dodecanese island profile, close to Symi, Rhodes, Karpathos, Cyprus, Kos, Kalymnos, Lycaonia Greeks, Nisyros, and Turkish Cypriot references.
The heatmap should emphasize Kastellorizo, Symi, Rhodes, Karpathos, Cyprus, Kos, Kalymnos, Nisyros, southern Anatolia, and the far eastern Aegean.
Greek Cyprus and Turkish Cyprus both appear among the close matches, reflecting Kastellorizo's far eastern Mediterranean position.
Yes. Symi and Rhodes are the two closest matches in this table.
The current reference has a small sample size and represents a very specific island, so related Dodecanese and Cypriot pages are important context.
