Sobre 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

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 23 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 23 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
