Admixture Calculator

Egy K7

**Egy K7 — 7-way ModernAncient admixture model** A compact, global admixture calculator that splits a genome into seven broad ancestry components (Amerindian, WHG, African, Near_East, Iran_N, Oceanian, East_Eurasian). Designed for researchers, students, and genetic genealogy users, Egy K7 highlights deep prehistoric signals and large-scale migration patterns, offering a clear, comparable snapshot of worldwide ancestry.

About This Calculator

**Egy K7 — ModernAncient 7-way Admixture Calculator** Egy K7 is a focused admixture calculator that decomposes an individual's genome into seven broad ancestry components using a mix of modern and ancient reference populations. It is built to highlight deep population structure and large-scale migration signals by comparing samples from anywhere in the world against seven informative reference groups: - **Amerindian** — Indigenous peoples of the Americas - **WHG (Western Hunter-Gatherers)** — Pleistocene–Holocene European foragers - **African** — Sub-Saharan African ancestry clade - **Near_East** — Levantine and Anatolian-related Near Eastern ancestry - **Iran_N** — Neolithic Iranian farmer-related ancestry - **Oceanian** — Papuan and other Melanesian/Oceanian ancestries - **East_Eurasian** — East Asian and related northern Eurasian ancestries What this calculator analyzes - Computes proportional contributions from the seven reference clusters to a test genome, producing a clear, comparable admixture profile. - Emphasizes ancient-to-modern continuity and major prehistoric influxes (e.g., Neolithic farming expansions, Pleistocene hunter-gatherer heritage, transcontinental migrations). Who it’s designed for - Researchers and students seeking a compact, interpretable 7-component view of ancestry. - Enthusiastic genetic genealogy users curious about broad, deep-time ancestry signals. - Anyone wanting a global-context snapshot that balances ancient and modern reference signals. Insights you can gain - Relative weights of broad ancestral streams shaping an individual's genome. - Signals of regional continuity (e.g., high Iran_N or Near_East in West Asia) or long-range contact (Amerindian/Oceanian/East_Eurasian traces). - A baseline for further, more fine-grained analyses. Why Egy K7 is valuable - Offers an accessible, interpretable 7-way model that captures major prehistoric and geographic structure without overfitting. - Useful as a teaching tool and a quick fi

Reference Populations

The populations used as genetic references in this calculator

7 Reference Populations

Amerindian
- Description: Indigenous peoples native to the Americas, possessing genetic ancestry primarily distinct from other continents.
WHG (Western Hunter-Gatherers)
- Description: Prehistoric European populations, predominantly found during the Mesolithic era.

African

African
- Description: Represents diverse populations across the African continent, characterized by high genetic diversity.

Near East

Near_East
- Description: Populations from the historical region encompassing the Middle East, known for early civilizations.
Iran_N (Neolithic Iran)
- Description: Refers to ancient populations from the region of modern-day Iran, significant for early agriculture development.

Oceania

Oceanian
- Description: Indigenous peoples of the Pacific Islands including Australia, Papua New Guinea, and the broader Pacific.

East Eurasian

East_Eurasian
- Description: Populations from eastern parts of Eurasia, combining diverse groups from East Asia to Siberia.

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 modern and ancient populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 7 reference populations
Modern & 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
Modern & Ancient populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
