Genetic Heatmap
See where your DNA is closest on the map. Paste your G25 coordinates and 1,998 modern populations light up, from deep red for your closest matches to pale yellow for the farthest.
How to read the heatmap: deep red marks the places whose populations are genetically closest to you, orange a medium distance and pale yellow the farthest. Each dot is the average of a modern population: hover or tap it to see your distance to it. Areas with no samples nearby stay blank.
Your G25 coordinates
Paste one line: a name, then the 25 numbers, separated by commas. Official and simulated G25 coordinates both work.
Your coordinates never leave your browser: the distances are computed on your device, and nothing is uploaded or stored.
Modern populations on the map
Paste your coordinates above, or try an example, to colour the map by genetic closeness.
Dark dots mark the places of your 10 closest populations. Click the map to zoom with your mouse wheel, or pinch on a phone.
Your closest populations
Your 25 closest modern populations will appear here, with their distance, how close that is, and a link to their page in the Population Atlas.
| # | Population | Distance |
|---|
Euclidean distance over the 25 G25 dimensions, lower is closer: very close is under 0.025, close under 0.050, moderate under 0.080 and distant beyond. Tap a name to find it on the map.
About these distances
The heatmap compares you with population averages, not with individual people, and a distance measures similarity, not an ancestry percentage. Neighbouring populations often look alike, each population is pinned to one point (often the centre of its region or country), and mixed ancestry tends to land between its sources. Read the map as a guide to where your DNA fits best among people living today.
Method: Euclidean distance over the 25 G25 dimensions to each of 1,998 modern population averages, computed in your browser. The colour surface blends the distances of nearby populations (inverse-distance weighting) and stays blank far from any sample. Population data generated 2 October 2026.
Thanks: to Davidski (Eurogenes), creator of Global25, and to Moriopoulos for the Moriopoulos Collection (non-simulated samples), the sources of most population averages used here, alongside ExploreYourDNA's own reference averages.
Keep exploring
Many populations on the map have their own page in the Population Genetics Atlas, linked from the popups and the table: their ancient make-up and their closest modern and ancient neighbours.
The Ancient Ancestry Maps use the same kind of map to show where 17 ancient ancestries, from steppe herders to Anatolian farmers, peak in modern populations.

Frequently asked questions
How does the Genetic Heatmap work?
It compares your G25 coordinates with about 2,000 modern population averages. For each one it measures the genetic distance, the straight-line (Euclidean) distance across the 25 dimensions of G25, then colours the map by blending the distances of nearby populations. The places whose populations are closest to you turn deep red, and the map zooms to them.
What do the colours mean?
On the site scale the colours follow fixed distance bands: deep red is very close (a distance under 0.025), red to orange is close (under 0.050), orange to yellow is moderate (under 0.080) and pale yellow is distant. The Relative scale stretches the same colours from your closest to your farthest population in the visible area, which helps to see the contrasts inside one region. Areas with no samples nearby stay blank.
Is my DNA uploaded anywhere?
No. You only paste 25 numbers, and every distance is computed by your own browser: nothing is sent to our server or stored. The share link contains your coordinates, so only share it with people you are happy to show them to.
Can I use simulated G25 coordinates?
Yes. Official G25 coordinates are calculated by Davidski from your raw DNA file and are the most precise. Simulated G25 coordinates, estimated from your raw file, work too: they are a little less precise, so read small differences between neighbouring populations with care. Both are available on our G25 coordinates page.
Why is my hotspot not exactly where my family comes from?
The map shows genetic similarity to population averages, not a family tree. Neighbouring populations often have very similar averages, some regions have more published samples than others, and mixed ancestry tends to land between its sources, so the hotspot can sit next to, or between, the places your family comes from.
