Add your profile, explore family origins and export coordinates from the area you choose.
Choose Add your data and sign in with Google. Paste your 25 G25 coordinates, select scaled or raw and indicate whether they are simulated. Add an approximate family-origin location, optional notes and haplogroups, then submit for review.
Browse without an account. Filter by country, region, haplogroup or source. Use Select area and mark two opposite corners on the map, then export the matching coordinates. Use the same format as your reference dataset.
You can also record each grandparent’s family-origin country and region. Filter for all four from one region, multiple regions, or incomplete information. These labels are self-reported and use the entered place names; they do not verify ancestry. New to G25? The sections below explain coordinates, DNA tests and haplogroups.
A community map where adults can choose to publish a pseudonym, scaled or raw G25 coordinates, an approximate family-origin location, and optional Y-DNA and mtDNA haplogroups. Approved profiles can be explored and exported for use in compatible tools.
Use a consumer autosomal DNA test, for example AncestryDNA, MyHeritage DNA or 23andMe. A sample is commonly collected from saliva or a cheek swab, depending on the kit.
When your results are ready, download your raw genotype file from your testing company. Keep that file private.
Request coordinates from a suitable service, or optionally generate an explicitly labeled K36-based simulation.
Sign in with Google, enter coordinates and an approximate location, read the privacy information and submit for moderation. Only approved profiles enter the public directory.
Register the kit, collect saliva and return the sample according to local shipping instructions. Kit instructions ↗
Activate the kit before sending it, then take the included cheek-swab sample. Activation ↗
Register the saliva tube before mailing, follow its collection instructions and send the package back. Getting started ↗
A genotyping array checks selected positions (SNPs) in your genome, often hundreds of thousands. It does not read your whole genome. It is commonly sufficient for ancestry analysis and a compatible G25 request.
WGS reads DNA across most of the genome and can yield much richer variant data. Coverage, quality and the downloadable file format still matter. A standard exported SNP file from a WGS service is not the same as the complete sequence.
MyHeritage has moved new laboratory samples to WGS; older kits may use an array, and the ordinary raw export may still be a SNP-style file. Check the actual technology and available exports for your kit. MyHeritage explanation ↗

Official instructions ↗Global25 (G25) represents a genetic sample with 25 coordinates in a principal-component space built from reference samples. The coordinates summarize patterns of genetic variation for exploratory population comparisons; they are not ancestry percentages, a nationality score or a medical result.
Coordinates multiplied by axis-specific scaling factors. Use these only with scaled reference datasets.
Unscaled coordinates in the same coordinate system. Use these only with raw reference datasets.
Do not combine scaled and raw coordinates in one comparison. A line usually contains a sample label followed by 25 comma-separated numbers.
The separate G25 Requests service currently advertises processing compressed DNA files (.zip or .gz) to calculate G25 coordinates. Check the current price, supported formats and its privacy policy on that site before paying or uploading. G25 Directory is not that service and does not receive the uploaded DNA file.
g25requests.app ↗If you have Eurogenes K36 admixture percentages, a K36-to-G25 simulator can estimate a 25-coordinate profile using a statistical conversion. One possible route is to obtain K36 results through GEDmatch, then paste them into a K36 simulator. Availability and access requirements depend on those third-party services.
A haplogroup is a branch of a genetic family tree, defined by shared inherited variants. It traces one ancestral line, rather than your entire ancestry.
The Y chromosome is usually passed from father to son. Its haplogroup follows your father, his father, and so on. A personal Y-DNA result requires a Y chromosome.
Mitochondrial DNA is inherited from your mother by children of either sex. It follows your mother, her mother, and so on; it is normally passed on through mothers. It is not the X chromosome.
Neither haplogroup describes all of your father’s or mother’s ancestry. People with the same haplogroup can have different autosomal ancestry.

Search by profile or place, choose a country or region, and select scaled or raw coordinates. Use the source filter to include or exclude simulations.
Choose the area-selection tool on the map and click two opposite corners of a rectangle. The area combines with your current filters. Clear the selection to search everywhere again.
Open the export dialog to review the number of profiles and the coordinate preview. Download the text file for a compatible analysis tool. Keep scaled and raw datasets separate.
Your new profile awaits moderation. Approval makes it visible to others. You can delete your own profile from its details. Demo profiles are fictional and must not be used for genetic analysis.
You may use a pseudonym, but genetic coordinates combined with family origin or haplogroups can still be identifying. Publish your own information only, use an approximate family-origin location rather than a home address, and remember that approved coordinates can be downloaded. Deleting a profile cannot recall previously exported copies.
