Global Ancestry K7
Global Ancestry K7 provides a clear, modern 7-way admixture breakdown for users worldwide. It estimates proportional ancestry across AMERINDIAN‑SIBERIAN, EAST‑ASIAN, SOUTHEAST‑ASIAN, NORTH‑EAST‑EUROPEAN, AFRICAN, SOUTH‑EUROPEAN, and SOUTH‑WEST‑ASIAN components—ideal for genealogy, education, and comparative research, translating complex genomic signals into an accessible biogeographic snapshot.

Global Ancestry K7 — Modern 7-way admixture calculator
What this calculator analyzes
Global Ancestry K7 uses genome-wide allele profiles to estimate an individual's proportional ancestry across seven broad reference components: AMERINDIAN‑SIBERIAN, EAST‑ASIAN, SOUTHEAST‑ASIAN, NORTH‑EAST‑EUROPEAN, AFRICAN, SOUTH‑EUROPEAN, and SOUTH‑WEST‑ASIAN. It models shared genetic drift and clustering patterns in modern and prehistorical populations to provide interpretable fractional ancestry estimates.
Who it's designed for
- Individuals worldwide seeking a high-level, interpretable view of biogeographic ancestry
- Genealogy enthusiasts cross-checking family history against genetic signals
- Researchers and students needing a compact, modern 7-way reference for comparative analyses
Insights you can gain
- Proportionate ancestry breakdown across seven continental/subcontinental axes
- Detection of major admixture components consistent with migration and contact events
- Contextual clues for recent vs. deep ancestral contributions when combined with dates or regional data
Historical and genetic context
These seven components reflect major population clusters shaped by Out‑of‑Africa dispersals, Holocene farming and steppe expansions, Indigenous peopling of the Americas and Siberia, and long histories of transcontinental contact (trade, migration, and conquest). The model simplifies a complex genomic landscape into actionable categories while preserving signals that map to well‑documented population histories.
Why this calculator is valuable
- Balances clarity and resolution: more informative than broad continental categories, yet more accessible than dozens of micro‑clusters
- Useful as a comparative tool across personal, genealogical, and academic projects
- Helps translate genomic data into a narrative that connects personal ancestry to global human history

As populações utilizadas como referências genéticas nesta calculadora
7 Poblaciones de referencia
AMERINDIAN-SIBERIAN:
- Represents the shared genetic ancestry between Native American populations (Amerindian) and indigenous Siberian groups. Reflects migrations across the Bering Strait and ancient links between the Americas and Eurasia.
EAST-ASIAN:
- Populations of East Asia, including Chinese, Japanese, Korean, and Mongolic groups. Known for genetic homogeneity and ties to ancient agricultural civilizations.
SOUTHEAST-ASIAN:
- Populations from Southeast Asia, including Thai, Vietnamese, Burmese, and Austroasiatic-speaking groups. Also encompasses Austronesian-speaking island populations, reflecting diverse genetic contributions from mainland and maritime sources.
NORTH-EAST-EUROPEAN:
- Populations from the northeastern regions of Europe, including Finnic, Baltic, and Slavic groups. Reflects Uralic and Indo-European influences, with genetic links to both Siberia and Western Europe.
AFRICAN:
- Broad genetic cluster encompassing populations from sub-Saharan Africa. Includes diverse ethnic groups with deep ancestral lineages, such as Bantu, Nilotic, and hunter-gatherer groups.
SOUTH-EUROPEAN:
- Populations from southern Europe, including Mediterranean groups such as Italians, Greeks, and Iberians. Reflects genetic influences from Neolithic farmers, ancient civilizations, and historical migrations.
SOUTH-WEST-ASIAN:
- Populations from Southwest Asia, encompassing the Arabian Peninsula, Levant, and parts of Mesopotamia. Known as a historical crossroads for early human migrations and cultural exchanges between Africa, Asia, and Europe.
Como interpretar a análise de mistura genética

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 7 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 7 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
