Sobre esta calculadora
Global Ancestry K23 2017 is a high-resolution admixture calculator that estimates an individual’s genetic ancestry using a model of 23 ancestry components (K=23) derived from 161 curated reference populations worldwide. It compares your genotype to a broad panel spanning Europe, the Near East, North Africa, Sub‑Saharan Africa, South and Southeast Asia, East Asia, Siberia, the Americas and Oceania to report proportional affinities and regional signals.
Who this calculator is for:
- Researchers seeking a compact, replicable K=23 overview of global ancestry
- Genealogists and adoptees exploring multi‑regional roots
- Enthusiasts curious about fine‑scale continental and subcontinental ancestry
What this calculator analyzes:
- Genome‑wide allele frequency patterns matched to 23 modelled components
- Relative contributions from 161 modern reference populations (e.g., Western and Eastern Europe, Levant, Arabian Peninsula, North Africa, South Asia, East Asia, Siberia, Indigenous American groups, Oceania, and diverse African populations)
Insights you can gain:
- Percent‑level breakdowns of major ancestry components and regional affinities
- Signals of recent admixture versus older shared ancestry
- Clues to migratory and historical contacts (e.g., Eurasian steppe, Mediterranean, Trans‑Saharan interactions)
Context and limitations:
- K=23 is a modern, statistical model — components are abstractions that summarize genetic structure, not “pure” historical populations.
- Results depend on reference sampling, allele frequencies, and quality of input genotype data. Interpret as probabilistic affinities, not definitive identities.
Why this calculator is valuable:
- Combines broad geographic coverage (161 populations) with a compact, interpretable K=23 framework to reveal subtle multi‑regional patterns
- Useful as an exploratory tool alongside haplogroup and segment‑based analyses for building hypotheses about ancestry

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
