Global Ancestry K9
Global Ancestry K9 — Ancient Admixture Overview
Quickly estimate ancient ancestry proportions across nine broad source populations (West African, Southeast Asian, South Asian, Pacific, European, Pygmy, WANA, Siberian, Native American). Designed for researchers and enthusiasts, K9 reveals deep-time affinities, highlights major prehistoric migrations, and provides an intuitive baseline for interpreting ancient and modern genomes. Model-based and best used with complementary evidence.

Global Ancestry K9 — Ancient Era Admixture Calculator
Global Ancestry K9 analyzes genome-wide autosomal patterns to estimate ancient ancestral contributions using a nine-population reference panel. Built around deep-time signals, this tool measures proportional affinity to nine broad ancient clusters: West African, Southeast Asian, South Asian, Pacific, European, Pygmy, West Asian–North African (WANA), Siberian, and Native American.
Who it's for:
- Genetic genealogists, archaeogeneticists, and history enthusiasts wanting clearer views of prehistoric ancestry
- Researchers comparing modern or ancient samples to broad continental and subcontinental source groups
- Anyone curious about deep ancestral components beyond recent genealogical pedigrees
What you gain:
- A proportional breakdown of inferred ancient ancestry across nine modeled sources
- Visual summaries (bar charts/clines) that highlight dominant and minor components
- Contextual interpretation that links proportions to major prehistoric migrations, such as Out-of-Africa dispersals, Holocene expansions, and peopling of the Americas and Oceania
Historical and genetic context: Global Ancestry K9 emphasizes macro-scale population structure relevant to the Ancient era. The nine reference groups represent long-standing regional lineages and demographic processes—hunter-gatherer substrata (Pygmy, Siberian), agricultural expansions (West Asian–North African, South Asian), maritime dispersals (Pacific, Southeast Asian), and continental clines (European, West African, Native American).
Why it matters:
- Translates complex allele-frequency patterns into intuitive ancestry components tied to archaeological and population-history narratives
- Helps formulate and test hypotheses about ancient admixture and migration routes
- Complements high-resolution studies by offering a clear, comparative baseline across major prehistoric source groups
Important note: K9 offers model-based approximations. Results reflect

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 9 cuidadosamente seleccionadas ancient populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 9 poblaciones de referencia
- Ancient 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
- Ancient se utilizan como referencias
- As percentagens indicam contribuições relativas no modelo
- Os resultados são estimativas baseadas nos dados de referência disponíveis
