One island, two communities—and each other’s closest genetic match.

The Greek Cypriot and Turkish Cypriot references have a genetic distance of just 1.158 in World Genetics’ Modern G25 comparison, classified as “Extremely close.” Each is the other’s nearest match in this reference set.

Their deep ancestry models tell a similar story. The same three components are the largest in both: Anatolian Neolithic Farmer, Levantine Neolithic Farmer and Zagros Neolithic Farmer ancestry.

The clearest difference is the balance between the first two. The Greek Cypriot reference has a higher Anatolian farmer-related estimate: 40.2%, compared with 34.2% for Turkish Cypriots. The Turkish Cypriot reference has more Levantine farmer-related ancestry in this model: 29.6%, compared with 25.8%.

Zagros farmer-related ancestry is much closer: 13.8% for Greek Cypriots and 14.6% for Turkish Cypriots. These are the three largest components; the rest of the model includes Caucasus hunter-gatherer and Western Steppe herder-related ancestry.

Their other nearby matches also point toward the eastern Mediterranean: Kastellorizo Greeks and Syrian Jews appear among the closest references for both.

Shared genetic proximity can sit alongside distinct languages and community histories. These are population averages and model estimates, so they don’t describe every person or define anyone’s identity.
