Global Ancestry K5
Global Ancestry K5 — 5‑way modern admixture calculator
A clear, world‑wide ancestry tool that estimates genome-wide proportions from five reference components: AMERINDIAN‑SIBERIAN, ASIAN, EUROPEAN, WEST‑ASIAN, and AFRICAN. Ideal for individuals, educators, and researchers who want a fast, interpretable snapshot of deep biogeographic ancestry and major historical admixture patterns. Not for fine-scale ethnicity or medical use.

Global Ancestry K5 — Modern-era 5-way admixture calculator
Global Ancestry K5 quantifies biogeographic ancestry using a compact, modern reference panel of five broad components: AMERINDIAN‑SIBERIAN, ASIAN, EUROPEAN, WEST‑ASIAN, and AFRICAN. It computes proportional contributions from each reference cluster to describe an individual or population's genome-wide ancestry profile.
What it analyzes
- Genome-wide allele patterns compared to five continental and subcontinental reference groups.
- Relative ancestry proportions expressed as percentages that sum to 100%.
- Broad admixture signals rather than fine-scale local ancestry or recent family-level genealogy.
Who it's designed for
- Individuals worldwide seeking a clear, interpretable summary of major ancestral components.
- Researchers and educators needing a reproducible, low-dimensional overview for population comparisons.
- Genetic genealogy users who want a rapid, high-level snapshot of deep ancestry.
What insights you can gain
- Approximate contribution of major human lineages to your genome (e.g., African vs. Eurasian vs. Indigenous American/Siberian).
- Signals of mixed ancestry consistent with documented migrations (Out-of-Africa dispersals, Eurasian expansions, peopling of the Americas, Siberian–American links).
- Comparative context across populations: which components dominate, and where admixture is complex.
Historical and genetic context
The five components reflect broad demographic events: ancient African origins, diversification into West and East Eurasian groups, migrations across Siberia into the Americas, and subsequent regional admixture. K5 prioritizes clarity over extremely fine regional resolution, making it ideal for interpreting macro-scale human history in modern genomes.
Why this calculator is valuable
- Clear, actionable results for both lay users and scientists.
- Fast, reproducible, and interpretable five-way breakdown useful for reports, teaching, and e

5 Poblaciones de referencia
AMERINDIAN-SIBERIAN:
- Represents the shared genetic ancestry of Native American populations (Amerindians) and indigenous Siberian groups. Highlights ancient migrations across the Bering Land Bridge and the genetic links between the Americas and northern Eurasia.
ASIAN:
- Includes populations across East, Southeast, South, and Central Asia. Reflects the genetic diversity of groups such as East Asians (Chinese, Japanese, Korean), South Asians (Indian, Pakistani), Southeast Asians (Vietnamese, Thai, Malay), and Central Asians (Kazakh, Uzbek). Captures ancient and diverse migration patterns across the continent.
EUROPEAN:
- Encompasses populations across the European continent, including Northern, Southern, Eastern, and Western European groups. Reflects genetic contributions from Neolithic farmers, Indo-European migrations, and interactions with neighboring regions.
WEST-ASIAN:
- Populations from the region encompassing the Levant, Anatolia, the Arabian Peninsula, and Mesopotamia. Known as a historical crossroads of early civilizations and human migrations, this cluster shows influences from ancient farmers and trade routes.
AFRICAN:
- Includes the diverse populations of sub-Saharan Africa, such as Bantu-speaking groups, Nilotic peoples, hunter-gatherers (e.g., San, Pygmies), and Sahelian communities. Represents the oldest genetic lineages and the birthplace of modern humans.
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 5 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 5 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
