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
Populações de referência
As populações utilizadas como referências genéticas nesta calculadora
7 Poblaciones de referencia
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
Como interpretar a análise de mistura genética
Descubra como funcionam as calculadoras de mistura genética e como interpretar os resultados
O que é a análise de mistura genética?
A análise de mistura genética estima a semelhança genética comparando o seu DNA com populações de referência de diferentes partes do mundo. Os componentes do modelo representam essas referências e dependem dos dados e pressupostos utilizados.
Esta calculadora utiliza 7 cuidadosamente seleccionadas ancient populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 7 poblaciones de referencia
- Ancient se utilizan como referencias genéticas
- Os resultados mostram a sua semelhança genética com estas populações
- A diversidade do painel de referência influencia as estimativas
Como interpretar seus resultados
Os resultados mostram percentagens de similaridade genética com estas populações de referência. Tenha presente estes pontos:
- Os resultados reflectem a semelhança genética, não ascendência directa demonstrada
- Ancient se utilizan como referencias
- As percentagens indicam contribuições relativas no modelo
- Os resultados são estimativas baseadas nos dados de referência disponíveis
