A focused population profile of Greeks from Achaea, their northern Peloponnesian background, closest modern genetic matches, ancestry model, and World Genetics G25 heatmap.
Greeks from Achaea come from the northern Peloponnese, including Patras, Aigio, Kalavryta, and coastal or mountain communities. Achaea's history includes ancient Achaean cities, Roman Patras, Byzantine and Frankish periods, Ottoman rule, the Greek War of Independence, and modern western Greek networks.
Greek is the main language. Achaea should be read as a northern Peloponnesian profile, linked to Elis, Arcadia, Argolis, Corinthia, Messenia, Laconia, Phocis, and southern Euboea.
As a genetic reference, Greek Peloponnese Achaea is useful for comparison with Elis, Arcadia, Euboea Chalcis South, Argolis, Laconia Vardounia/East Taygetos, Corinthia, Messenia, Phocis, and Laconia.
In the World Genetics modern G25 comparison, the closest non-self match for Greek Peloponnese Achaea is Greek Peloponnese Elis. Other nearby references include Greek Peloponnese Arcadia, Greek Euboea Chalcis (South Euboea Profile), Greek Peloponnese Argolis, and Greek Peloponnese Corinthia. This gives the Greek Peloponnese Achaea profile its nearest modern genetic context inside the current reference database.

The ancestry breakdown gives deeper component proportions, while closest matches show modern similarity. Achaean Greek is best interpreted as a northern Peloponnesian profile, close to Elis, Arcadia, Argolis, Corinthia, Messenia, Laconia, Phocis, and southern Euboea.
The heatmap should emphasize Achaea, Patras, Elis, Arcadia, Argolis, Corinthia, Messenia, Laconia, Phocis, and southern Euboea.
The closest non-self match in this World Genetics comparison is Greek Peloponnese Elis. Other nearby references include Greek Peloponnese Arcadia, Greek Euboea Chalcis (South Euboea Profile), Greek Peloponnese Argolis, and Greek Peloponnese Corinthia.
In the current modern G25 reference set, Greek Peloponnese Elis is the closest listed match to the Greek Peloponnese Achaea average after removing Greek Peloponnese Achaea itself from the table.
The heatmap shows where modern reference populations are closer or farther from the Greek Peloponnese Achaea G25 average, giving the closest-match results a geographic view.
