Description
DNA Genics World K28 is a modern, high-resolution admixture calculator that estimates the proportional ancestry of an individual across 28 global genetic components built from 23 reference population clusters. Designed for geneticists, genealogists, ancestry enthusiasts and researchers, the tool converts genome-wide genotype data into a clear portrait of regional affinities—from broad continental signals (e.g. Broadly African, East Asian, West European) to more specific regional clusters (e.g. East Med, West Med, Anatolian, Finnic and Broadly Central Asian).
What it analyzes: the calculator compares your genotype to curated reference sets representing contemporary population structure and returns percentage contributions for each K28 component. Outputs are suitable for visual inspection (stacked bar charts, continental breakdowns) and for downstream analysis such as cluster comparison, PCA anchoring or lineage hypothesis testing.
What you can learn: discover primary and minor ancestral inputs, detect multi-regional mixtures (for example, Eurasian steppe, Near Eastern, Sub-Saharan, or Amerindian signals), and place your personal profile in historical context—migration corridors, expansions (Neolithic farmers, Steppe pastoralists, Bantu and Arab expansions), and recent admixture events (colonial era, Silk Road connectivity, transatlantic movements).
Why it’s valuable: by combining broad and region-specific reference groups the K28 model balances resolution and interpretability—helping users separate deep prehistoric ancestry from more recent regional gene flow. It’s a practical tool for building genealogical leads, informing population studies, and educating about human genetic diversity.
Important notes: results depend on reference composition, marker overlap and statistical modeling. Categories are simplified representations, not precise ethnic identities. Use results as a guide alongside historical, archaeological and documentary evidence for a rounded underst
Reference Populations
Africa:
- Broadly African: Refers to a general genetic heritage from the African continent without specific regional emphasis.
- East African: Populations primarily from countries like Kenya, Ethiopia, and Somalia.
- West African: Populations from regions including Nigeria, Ghana, and Senegal.
Americas:
- Amerindian: Indigenous peoples of North and South America.
Asia:
- Anatolian: Populations located in present-day Turkey, historically known as Asia Minor.
- Broadly Central Asian: Encompasses populations from countries such as Kazakhstan and Uzbekistan.
- Broadly Indian: Covers the Indian subcontinent, including India, Pakistan, and Bangladesh.
- East Asian: Incorporates populations from China, Japan, and Korea.
- South Asian: Primarily focuses on populations from India, Pakistan, Bangladesh, and Sri Lanka.
- West Asian: Encompasses populations from regions like Iran and the Arabian Peninsula.
Europe:
- Broadly Balkan: Refers to populations from Southeast Europe including countries like Greece, Bulgaria, and Serbia.
- Broadly Caucasian: Covers the ethnic diversity of the Caucasus region, including Armenia, Azerbaijan, and Georgia.
- Broadly Levantine: Encompasses populations from Lebanon, Syria, Jordan, and Israel.
- Broadly North African: Refers to populations from the Maghreb region, including Morocco and Algeria.
- Broadly Peninsula Arab: Populations from the Arabian Peninsula.
- Eastern European: Originates from countries like Russia, Poland, and Ukraine.
- Finnish: Populations exclusively from Finland.
- West European: Encompasses populations from countries such as France, Germany, and the UK.
Oceania:
- West Med: Often a misnomer, but typically relates to populations around the Mediterranean region, primarily referring to the Western part.
Other:
- Broadly Horn of Africa: Populations from areas such as Somalia, Ethiopia, and Eritrea.
- Broadly Siberian: Relates to indigenous peoples from Siberian regions.
- East Med: Populations from Eastern Mediterranean areas, including Cyprus and surrounding countries.
- North African: Populations from countries such as Egypt, Libya, and Tunisia.
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
