About This Calculator

**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

Reference Populations

The populations used as genetic references in this calculator

7 Reference Populations

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

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

What is Admixture Analysis?

Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.

This calculator uses 7 carefully selected ancient populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 7 reference populations
Ancient populations are used as genetic references
Results show your genetic similarity to these populations
More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

Results reflect genetic similarity, not direct ancestry
Ancient populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
