Global Ancestry K33 2023
Global Ancestry K33 2023 — A high-resolution global admixture calculator using 33 reference populations. It estimates proportional ancestry across Africa, Eurasia, the Americas and Oceania while excluding Jewish reference clusters, offering a clear, non-Jewish baseline for genealogy, population studies and personal exploration. Results are model-based estimates, not medical or legal determinations.

Global Ancestry K33 2023
This calculator analyzes an individual's autosomal DNA and estimates proportional ancestry using a 33-population global reference panel. Built for the modern era (K=34 structure) it provides a fine-grained admixture breakdown across Eurasia, Africa, the Americas and Oceania while intentionally omitting Jewish reference clusters to provide a non-Jewish baseline.
What this calculator analyzes:
- Genome-wide allele frequencies compared to 33 geographically and culturally informed reference populations
- Relative proportions that best explain an individual's genetic makeup in the context of recent and long-term admixture
Who it's designed for:
- Genealogy enthusiasts and direct-to-consumer DNA users seeking a clearer global picture
- Population genetics students and researchers needing a broad, cross-continental baseline
- People curious about regional signals without the influence of Jewish reference clusters
Key insights you can gain:
- Percentage breakdowns of ancestry components (e.g., West-Asian, Scandinavian, West-African, Native-American)
- Detection of mixed continental ancestry and subtle regional contributions
- A framework to interpret historical migration, trade and demographic events reflected in your genome
Historical and genetic context:
- Modern human populations reflect layered histories: ancient expansions, recent migrations and local admixture
- This calculator interprets those layers through contemporary reference samples, highlighting geographic clines (e.g., Eurasian, African, East Asian) and island/Oceanian signatures
Why this calculator is valuable:
- Broad, global coverage with 33 reference populations gives balanced resolution across continents
- The deliberate exclusion of Jewish clusters offers an alternative comparative baseline for users who prefer or require that context
- Clear, interpretable output suitable for both non-specialists and informed users

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 34 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 34 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
