A focused population profile of Greeks from Chalcis in central Euboea, their island-mainland background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Greeks from Chalcis are associated with central Euboea, the large island just off mainland central Greece. Chalcis has long been a bridge between Euboea, Boeotia, Attica, the Aegean, and the Greek mainland, with history going back to ancient Euboean city-states, Byzantine and Venetian periods, Ottoman rule, and modern regional movement.
Greek is the main language. This reference is specifically a Central Euboea profile, so it should be compared with other Euboean profiles, Crete, the Cyclades, the Dodecanese, Campania, and Peloponnesian Greek references.
As a genetic reference, Greek Euboea Chalcis Central is useful for comparison with Cretan, Deep Mani, Chania, Lasithi, Rethymno, Paros, Astypalaia, and other Aegean or southern Greek references.
In the World Genetics modern G25 comparison, the closest non-self match for Greek Euboea Chalcis (Central Euboea Profile) is Greek Crete Heraklion. Other nearby references include Greek Peloponnese Laconia Mani, Greek Crete Chania, Greek Crete, and Greek Cyclades Milos. This gives the Greek Euboea Chalcis (Central Euboea Profile) profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Chalcis Central Euboea is best interpreted as an Aegean Greek profile, close to Cretan, Deep Mani, Cycladic, Dodecanese, and some southern Italian references.
The heatmap should emphasize Euboea, Chalcis, Crete, Laconia/Mani, Paros, Astypalaia, Campania, and the central/southern Aegean.
The closest non-self match in this World Genetics comparison is Greek Crete Heraklion. Other nearby references include Greek Peloponnese Laconia Mani, Greek Crete Chania, Greek Crete, and Greek Cyclades Milos.
In the current modern G25 reference set, Greek Crete Heraklion is the closest listed match to the Greek Euboea Chalcis (Central Euboea Profile) average after removing Greek Euboea Chalcis (Central Euboea Profile) itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Greek Euboea Chalcis (Central Euboea Profile) G25 average, giving the closest-match results a geographic view.
