GENOSTRUCT

Archaic markers explorer

Trace Neanderthal and Denisovan markers in your genome

Upload AncestryDNA, 23andMe, or FTDNA raw data to quantify archaic signal rates, compare against global reference panels, and surface standout variants that distinguish your archaic markers.

We read the markers required for archaic markers modelling. Works with AncestryDNA, 23andMe, and FTDNA exports.

The file is analysed securely in one session and never persists on our servers.

Methodology Overview

Neanderthal and Denisovan Signal Quantification

Small segments of Neanderthal and Denisovan DNA are present in many people today. These segments act as signals that allow us to compare your genome against curated regional references.

Genostruct measures your match rate at specific "archaic-informative" marker positions—variants that were fixed in archaic hominins but absent or rare in early modern human populations.

Reference Panels
Scores are benchmarked against internally curated modern percentile references including West Asia, East Asia, Northern/Western Europe, and Australian Aboriginal populations.
Provider Support
Optimized for 23andMe, AncestryDNA, and FTDNA raw exports.

Archaic Signal FAQ

How do I get my raw data file?

Export it from your 23andMe, AncestryDNA, or FTDNA account and upload the ZIP/TXT/CSV here.

Is this a percentage of ancestry?

The score reflects match rates at archaic-informative markers, not a direct ancestry percent. Higher scores simply mean more of your allele states match the archaic-assumed variants at those informative SNPs within our reference framework.

Which regions tend to show stronger signals?

Some Eurasian groups commonly show stronger archaic signals than other world regions in our references.

What references are used?

Genostruct uses internally curated modern percentile references. Current reference regions include Northern and Western Europe (e.g. Scandinavian, Scottish, and French samples), West Asia, East Asia, Australian Aboriginal populations, and Mbuti. The archaic-informative markers used for Neanderthal and Denisovan signal modelling were originally defined using comparisons against Mbuti. As regional references are expanded or refined, percentile ranges may shift slightly.
