Admixture Calculator

Global Ancestry K4

**Global Ancestry K4 — continental-scale admixture in four clusters** A fast, accessible calculator that estimates an individual's DNA proportions across four global reference groups: **ASIAN**, **AFRICAN**, **AMERINDIAN‑SIBERIAN**, and **EUROPEAN‑WESTASIAN**. Ideal for curious individuals, genealogists, educators, and researchers seeking a clear, scientifically grounded overview of major ancestral contributions. Provides percentages, visual placement, and historical context as a reliable start

About This Calculator

**Global Ancestry K4 — Clear, global-scale admixture profiling** Global Ancestry K4 analyzes a DNA sample against four broad reference clusters — **ASIAN**, **AFRICAN**, **AMERINDIAN‑SIBERIAN**, and **EUROPEAN‑WESTASIAN** — to produce an interpretable, modern-era picture of continental-scale ancestry. It quantifies the proportion of genetic ancestry attributed to each cluster and visualizes where an individual's genome sits on major global clines. Who it's for - Individuals curious about broad ancestral roots and major continental contributions. - Genealogists seeking a high-level complement to family history. - Educators and students learning about human population structure. - Researchers wanting a simple, reproducible K=4 baseline for comparative studies. What you get - Percent admixture breakdown across the four reference groups. - A graphical representation of affinity to each cluster and relative position among reference populations. - Interpretive notes connecting proportions to historical processes (e.g., migrations, trade, colonialism, and population mixtures). Genetic and historical context Human genetic diversity is shaped by repeated migrations, isolation, and admixture. The four clusters in K4 capture deep continental-scale signals: east–west Eurasian gradients, the out-of-Africa diversity of Africa, the peopling of the Americas via Siberia, and later complex Eurasian mixtures. This calculator situates modern genomes within those overarching patterns. Why use Global Ancestry K4 - Fast, robust overview: a clear starting point before moving to higher-resolution analyses. - Intuitive interpretation: useful for non-specialists while remaining scientifically grounded. - Comparative value: standardized K=4 results are easy to compare across datasets and studies. Limitations (brief) K4 is intentionally coarse; it does not resolve fine-scale ethnicities, recent migration nuances, or specific tribal lineages. Results depend on reference composition and ref

Reference Populations

The populations used as genetic references in this calculator

4 Reference Populations

ASIAN: Encompasses the genetic diversity of populations across East, Southeast, South, and Central Asia. Includes groups such as East Asians (Chinese, Japanese, Korean), South Asians (Indian, Pakistani), Southeast Asians (Thai, Vietnamese, Malay), and Central Asians (Kazakh, Uzbek). Represents a rich tapestry of ancient migrations and linguistic families.
AFRICAN: Covers the genetic spectrum of sub-Saharan Africa, including Bantu-speaking populations, Nilotic groups, hunter-gatherers like the San and Pygmies, and Sahelian populations. Represents some of the deepest genetic lineages of humankind.
AMERINDIAN-SIBERIAN: Represents the shared ancestry between Native American populations (Amerindians) and indigenous Siberian groups. Reflects ancient migrations across the Bering Land Bridge and the genetic ties between the Americas and northern Eurasia.
EUROPEAN-WESTASIAN: Combines populations from Europe and West Asia, reflecting genetic continuity and interaction through ancient migrations and historical civilizations. Includes European groups (e.g., Slavic, Germanic, Mediterranean) and West Asian groups (e.g., Anatolian, Levantine, Mesopotamian). This cluster demonstrates significant Neolithic farmer and Indo-European influences.

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 4 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 4 reference populations
Modern 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 populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
