Modern World Kakaji K20
Modern World Kakaji K20 offers a 20-population admixture breakdown that maps your DNA to a curated panel spanning Africa, Europe, the Middle East, South & East Asia, Siberia, and the Americas. Ideal for genetic genealogy, research, and education, it provides interpretable ancestry proportions and insights into recent gene flow and regional affinities — with clear caveats about model dependence.

Modern World Kakaji K20 — What this calculator analyzes
This calculator decomposes an individual genotype into contributions from 20 modern reference populations, producing a fine-grained admixture profile for the contemporary world. It compares your DNA to a curated panel that spans Sub-Saharan Africa, North Africa and the Middle East, Europe, South Asia, East and Northeast Asia, Siberia, and Indigenous America to estimate relative ancestry proportions.
Who it’s designed for
- Genetic genealogy enthusiasts seeking regional affinities
- Researchers and students exploring population structure and recent admixture
- Educators demonstrating real-world examples of human genetic diversity
Reference panel highlights
Includes representative groups such as Lahu, Naxi, Dai, Japanese, Yakut (East & Northeast Asia); Tamil, Telegu, Makrani, Kalash (South & Central Asia); Finn, Sardinian (Europe); Druze, Bedouin, Mozabite (Middle East/North Africa); Gambian, Esan, Mbuti and Biaka Pygmies (diverse African ancestries); and Karitiana, Pima (Indigenous America).
Insights you can gain
- Quantitative ancestry proportions against 20 modern populations
- Detection of mixed regional signals (for example, South Asian + West Eurasian or East Asian + Siberian)
- Clues about recent gene flow, historical migrations, and population contact zones
Historical and genetic context
The panel reflects both ancient deep splits (e.g., Sub-Saharan vs. non‑African) and recent regional structure shaped by migrations, trade, and isolation (e.g., island Sardinian drift, Siberian Yakut ancestry, Andean/Amazonian Americas). The inclusion of pygmy and Saharan/North African references helps resolve African substructure often missed in coarse models.
Why this calculator is valuable
- Provides a balanced, interpretable K=20 breakdown that is more granular than broad continental models
- Useful for mapping likely regional affinities and recent admixture events
- A practical teach

Como interpretar a análise de mistura genética
Descubra como funcionam as calculadoras de mistura genética e como interpretar os resultados
O que é a análise de mistura genética?
A análise de mistura genética estima a semelhança genética comparando o seu DNA com populações de referência de diferentes partes do mundo. Os componentes do modelo representam essas referências e dependem dos dados e pressupostos utilizados.
Esta calculadora utiliza 20 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 20 poblaciones de referencia
- Modern se utilizan como referencias genéticas
- Os resultados mostram a sua semelhança genética com estas populações
- A diversidade do painel de referência influencia as estimativas
Como interpretar seus resultados
Os resultados mostram percentagens de similaridade genética com estas populações de referência. Tenha presente estes pontos:
- Os resultados reflectem a semelhança genética, não ascendência directa demonstrada
- Modern se utilizan como referencias
- As percentagens indicam contribuições relativas no modelo
- Os resultados são estimativas baseadas nos dados de referência disponíveis
