Eurogenes K7 AMI
Eurogenes K7 AMI — Ancient-era European admixture calculator
A compact 7-component admixture model tailored for ancient-era European analysis. It reports proportional affinities to Sub-Saharan, Oceanian, Amerindian, Euro_HG, Siberian, Southeast_Asian, and Near_Eastern clusters. Ideal for archaeogeneticists, students, and enthusiasts who want a clear, interpretable overview of major prehistoric ancestry signals and unexpected admixture in European samples.

Eurogenes K7 AMI — Ancient-era admixture calculator for Europe
This calculator estimates ancestry proportions using a compact, archaeogenetically informed 7-component model optimized for European samples in the Ancient era. It compares a tested genotype against seven reference clusters: Sub-Saharan, Oceanian, Amerindian, Euro_HG, Siberian, Southeast_Asian, and Near_Eastern. The result describes how much of an individual's genome best matches each ancestral cluster.
Who it’s for:
- Researchers, students, and enthusiasts working with ancient European specimens or modern individuals seeking an ancient-aware breakdown.
- Anyone interested in broad continental and prehistoric migration signatures rather than fine-scale modern population structure.
What you can learn:
- Proportional affinities to European hunter-gatherers (Euro_HG) and Near Eastern farming groups (Near_Eastern).
- Signals of northern/eastern influx (Siberian) associated with steppe or Siberian-related ancestry.
- Presence of distal or unexpected components (Sub-Saharan, Oceanian, Amerindian, Southeast Asian) that indicate deep or recent admixture, contamination, or model artifacts.
Context and scientific grounding:
- K7 is a compact admixture framework: each component is a simplified cluster representing broad ancestral sources rather than named historical populations.
- Euro_HG reflects pre-agricultural hunter-gatherer ancestry in Europe; Near_Eastern captures agriculturalist-derived input; Siberian and others capture Eurasian steppe or far-eastern contributions and non-Eurasian affinities.
Why this calculator is valuable:
- Fast, interpretable overview useful for hypothesis generation, sample triage, and public-facing summaries.
- Especially helpful for ancient DNA projects where reduced-component models minimize overfitting and clarify major migratory events.
Limitations & best practices:
- Results depend on chosen reference panels; components are heuristic and s
Referenzpopulationen
Die in diesem Rechner als genetische Referenzen verwendeten Populationen
7 Referenzpopulationen
Sub-Saharan: Represents populations from the African continent, encompassing a wide genetic diversity with historically deep-rooted lineages.
Oceanian: Includes populations from the regions of Papua New Guinea, Australia, and surrounding islands, known for their unique genetic adaptations.
Amerindian: Refers to Indigenous peoples of the Americas, with diverse groups ranging from North to South America and distinct ancestral lineages.
Euro_HG: Represents European Hunter-Gatherers, early inhabitants of Europe dating back to pre-agricultural times.
Siberian: Covers populations in the Siberian region, traditionally linked to rugged environmental adaptations and connections to Native American ancestry.
Southeast_Asian: Encompasses diverse ethnic groups from countries in Southeast Asia, characterized by complex migratory histories.
Near_Eastern: Consists of populations from the Near East, a historical crossroads of human civilization and diversity.
Grouped by Continent:
- Africa: Sub-Saharan
- Oceania: Oceanian
- Americas: Amerindian
- Europe: Euro_HG
- Asia: Siberian, Southeast_Asian, Near_Eastern

Was ist eine Admixture-Analyse?
Bei einer Admixture-Analyse wird Ihre genetische Ähnlichkeit geschätzt, indem Ihr DNA mit Referenzpopulationen aus verschiedenen Weltregionen verglichen wird. Die Komponenten des Modells stehen für diese Referenzen und hängen von den zugrunde liegenden Daten und Annahmen ab.
Dieser Rechner nutzt 7 sorgfältig ausgewählte ancient Populationen als Referenzen und ermöglicht eine detaillierte Darstellung Ihrer genetischen Ähnlichkeit.
So funktioniert es
- Ihr DNA wird mit 7 Referenzpopulationen verglichen
- Ancient-Populationen dienen als genetische Referenzen
- Die Ergebnisse zeigen Ihre genetische Ähnlichkeit zu diesen Populationen
- Ein vielfältiges Referenzpanel verbessert die Schätzungen
Ihre Ergebnisse verstehen
Ihre Ergebnisse zeigen Prozentsätze der genetischen Ähnlichkeit zu diesen Referenzpopulationen. Beachten Sie diese Punkte:
- Die Ergebnisse spiegeln genetische Ähnlichkeit wider, nicht nachgewiesene direkte Abstammung
- Ancient-Populationen werden als Referenzen verwendet
- Die Prozentsätze geben relative Beiträge im Modell an
- Die Ergebnisse sind Schätzungen auf Basis der verfügbaren Referenzdaten
