Acerca de esta calculadora
Global Ancestry K23 2023 is a modern, high-resolution admixture calculator (K = 23) that analyzes autosomal genotype data to estimate the proportion of ancestral components drawn from a worldwide set of reference populations. It is built to identify continental- and subcontinental-level ancestry signals and to help users translate their DNA into geographic and historical context.
What this calculator analyzes
- Percent contributions of 23 reference populations across Africa, Europe, Asia, Oceania and the Americas
- Broad and fine-scale ancestry signals that reflect recent and ancient admixture
- Autosomal patterns that represent the combined inheritance from all ancestral lines
Who this is designed for
- Consumers exploring personal ancestry and ancestry enthusiasts
- Genealogists and adoptees seeking biogeographic clues
- Researchers and students who need a compact K=23 reference for comparative analyses
Insights you can gain
- A proportional breakdown of likely ancestral sources (e.g., West African, Near Eastern, South Asian, Melanesian, Native American)
- Clues about past migrations and contact zones (e.g., Bantu expansions, Eurasian steppe movements, colonial-era admixture, Austronesian dispersals)
- A clearer picture of multi-continental heritage and unexpected minor components
Reference populations include: Benin Togo; Africa Southeastern Bantu; Cameroon Congo; Mali; Senegal; Africa North; Ivory Coast Ghana; Nigeria; Caucasus; Asia Central; Asia South; Near East; Asia East; Europe East; Finland Northwest Russia; Europe West; Iberian Peninsula; Great Britain; Italy Greece; Ireland; Scandinavia; Melanesia; Native American.
Historical and genetic context
- By comparing an individual to geographically and linguistically informed reference groups, the calculator frames ancestry in terms of major demographic events — migrations, trade routes, colonization, and long-term regional continuity.
Why this calculator is valuable
- Offers a balanced, interpretable

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 23 cuidadosamente seleccionadas modern poblaciones como referencias para describir con detalle la similitud genética.
Cómo funciona
- Tu ADN se compara con 23 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
