Description
Modern World K28 is a curated K=28 admixture calculator designed to dissect contemporary global ancestry into 29 well-chosen reference components. It analyzes autosomal DNA to estimate the proportional contributions from modern and regionally informative populations — from African hunter-gatherers, Bantu and West African groups to Europe’s British, Iberian, Italian and Balkan clusters; from diverse Asian components including South, East, NorthEast and Southeast Asia, to Central Asian (Iranic, North, South) and Austronesian signals; and to Oceanian and Indigenous American ancestries. Built for a broad audience — genetic genealogists, population geneticists, anthropologists, and curious individuals with diverse backgrounds — this tool translates genome-wide variation into accessible regional affinities.
Users gain quantitative insights into recent and relatively deep ancestry: which continental and regional lineages are present, approximate proportion estimates, and comparative affinities among neighboring populations. Because the reference set is curated for the modern era, it highlights patterns shaped by historical migrations and demographic events such as the Bantu expansion, Eurasian steppe movements, Mediterranean and Balkan admixture, Austronesian dispersal, and Native American roots, while also distinguishing finer European and Asian substructure.
Modern World K28 is valuable because it balances global breadth with regional resolution. It helps validate other ancestry reports, guides further genealogical research, and provides teaching-ready results for understanding how historical population dynamics are reflected in individual genomes. Results are best interpreted alongside historical, archaeological, and genealogical context: proportions are model estimates, not definitive labels, but they offer a clear, quantitative snapshot of how an individual’s DNA relates to contemporary world populations.
Reference Populations

- African Hunter-Gatherers: Indigenous populations relying on hunting and gathering.
- Bantu: Widespread ethnic groups across sub-Saharan Africa.
- North Africa: Populations from countries like Algeria, Egypt, and Morocco.
- North East Africa: Regions including the Horn of Africa, such as Ethiopia and Somalia.
- West African: Populations from West African nations like Nigeria and Ghana.
Asia
- Central Asia (Iranic): People from Iran and surrounding areas with Iranian languages.
- Central Asia (North): Turkic and other groups from Kazakhstan and neighboring regions.
- Central Asia (South): Populations from regions like Uzbekistan and Turkmenistan.
- East Asia: Populations from countries like China, Korea, and Japan.
- NorthEast Asia: Siberian and Far Eastern Russian populations.

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 28 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.
How It Works
Key Points
- Your DNA is compared to 28 reference populations
- Modern populations are used as references
- Results show your genetic similarity to these populations
Understanding Your Results
Your results will show percentages of genetic similarity to these reference populations. Remember:
- Results reflect genetic similarity, not direct ancestry
- Modern populations are used as references
- Percentages indicate relative genetic contribution from each population
- Results are estimates based on available reference data
