Global Ancestry K25
This calculator estimates an individual's autosomal ancestry as proportions across a 25‑component modern reference panel (K25). It quantifies how much genetic affinity you share with geographically and historically informed populations from Africa, Europe, Asia, the Middle East, and Oceania.
What this analyzes
- Autosomal admixture proportions against 26 modern reference populations (e.g., East_European, Anatolia_Caucasus_Iranian_Plateau, Bengal, West_African, Oceania).
- Relative genetic affinity reflecting recent and deep population history rather than strict “labels.”
Who it’s designed for
- Genetic genealogy enthusiasts seeking finer regional resolution.
- Population geneticists and students needing a modern multi‑regional baseline.
- Anyone curious about ancestral composition across Eurasia, Africa, and Oceania.
Insights you can gain
- Proportions of ancestry tied to major geographic and historical planes: Near Eastern farmer and Caucasus-related signals, Steppe/north‑central Asian influences, South and Southeast Asian components, African regional distinctions, and Oceanian signatures.
- Clues about migration, admixture, and recent regional contact when combined with dates or family history.
Historical and genetic context
This panel reflects modern population structure shaped by events such as post‑glacial recolonization, the Neolithic transition from Anatolia and the Iranian plateau, Bronze Age Steppe movements into Europe and South Asia, maritime expansions in Southeast Asia and Oceania, and long‑distance dispersals across Africa and Eurasia.
Why it’s valuable
- Offers fine-grained, interpretable components for comparative analyses.
- Useful as a cross‑check against other calculators and for identifying unexpected admixture signals.
Caveats
- Results depend on reference sampling and mode

Cómo interpretar el análisis de mezcla genética
Descubre cómo funcionan las calculadoras de mezcla genética y cómo interpretar los resultados
¿Qué es el análisis de mezcla genética?
El análisis de mezcla genética estima la similitud genética comparando tu ADN con poblaciones de referencia de distintas partes del mundo. Los componentes del modelo representan esas referencias y dependen de los datos y supuestos utilizados.
Esta calculadora utiliza 25 cuidadosamente seleccionadas modern poblaciones como referencias para describir con detalle la similitud genética.
Cómo funciona
- Tu ADN se compara con 25 poblaciones de referencia
- Modern se utilizan como referencias genéticas
- Los resultados muestran tu similitud genética con estas poblaciones
- La diversidad del panel de referencia influye en las estimaciones
Cómo interpretar tus resultados
Los resultados muestran porcentajes de similitud genética con estas poblaciones de referencia. Ten presentes estos puntos:
- Los resultados reflejan similitud genética, no ascendencia directa demostrada
- Modern se utilizan como referencias
- Los porcentajes indican contribuciones relativas en el modelo
- Los resultados son estimaciones basadas en los datos de referencia disponibles
