The short answer: MyHeritage does not and cannot give you Global25 coordinates. No testing company does. What MyHeritage gives you is a raw data export, and that file is what the independent Eurogenes Global25 service turns into a coordinate row. This guide covers the MyHeritage-specific half of the route — including one caveat unique to MyHeritage that regularly surprises people. The full background is in the main guide.
Step one: download your MyHeritage raw data#
Go to DNA → Manage DNA kits → Download kit. Like AncestryDNA (and unlike 23andMe), the file is not handed over immediately: MyHeritage emails the download rather than serving it on the spot, so expect a short wait and check spam if nothing arrives.
The export is a .zip holding a .csv of genotype calls. Keep it somewhere stable — it is the
input to everything below.
The low-pass WGS caveat#
MyHeritage's standard chip test covers autosomes plus a set of Y-chromosome and mitochondrial positions. Its low-pass whole-genome product is different: the export carries autosomes and X only — no Y-chromosome rows and no mitochondrial rows at all.
For Global25 this does not matter — the coordinate is computed from autosomal data. But if you also wanted a paternal or maternal haplogroup, a low-pass MyHeritage export simply cannot support one, and no amount of re-uploading changes that. The fastest way to know which kind of file you have is our free raw DNA file check: it parses the export, counts usable markers per chromosome, and says plainly which analyses can read it. Nothing is ordered and nothing is stored.
If your file does carry the uniparental rows, it works in our free Y-DNA clade finder and mtDNA haplogroup finder.
Step two: the file becomes a coordinate#
Global25 coordinates are issued by Davidski's independent Eurogenes Global25 service — the G25 Requests portal at g25requests.app — not by MyHeritage, and not by us. Upload the raw file there, pay their €15 per-kit fee, and receive your row; their site states 2–7 days. The process and terms are the service's own and have changed more than once, so their posting is the only authority on the details. You will receive scaled and unscaled forms of your row: keep both, keep them labelled, and never mix the two in one comparison.
Rather not handle the request yourself? Upload this same file with an Ancestrify Global25 analysis and, with your consent, we obtain your official coordinates for you from that very service (+€15, typically a few days) — your full analysis runs the moment they arrive, and the row stays yours to keep.
And treat "free G25 generators" for what they are: converters that simulate a row from another calculator's output, describing the conversion rather than your genome. Our authenticity check reads a row's numeric fingerprint if provenance is ever in doubt.
Step three: use the row#
With a real coordinate row, all of this is free, in your browser, no account:
- Rank your closest ancient and modern populations, era by era, in the G25 distance calculator.
- Model your ancestry against curated source panels in the Global25 admixture calculator.
- Plot yourself on ancient-DNA PCA views in the G25 PCA viewer.
For the full worked report — distances, admixture and PCA across six eras with cinematic exports — see our Global25 analysis. If you would rather submit the raw MyHeritage file itself and get a formal, testable model with p-values, that is our qpAdm analysis, which takes the raw file directly.
