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
参考人口
计算器中用作遗传参考的种群
5 Reference Populations
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.

什么是“混合分析”?
混合分析是用来通过将你的DNA与来自世界各地的参考人群进行比较来估计你的基因祖先的一种方法。 把它看作是创造了你的基因化妆的食谱, 即成分是不同的祖先种群。
此计算器使用 5 仔细选择 modern 作为参考,可以详细分解您的遗传遗产。
如何运作
- 将您的 DNA 与 5 个参考人群进行比较
- 以 Modern 人群作为遗传参考
- 结果显示你的基因与这些种群相似
- 使用不同的参考面板更准确
了解你的成果
您的研究结果将显示与这些参考人群的遗传相似性的百分比。请记住这些要点:
- 结果反映了遗传相似性,而不是直接祖先
- Modern populations are used as references
- 表明相对遗传贡献的百分比
- 结果是根据现有参考数据作出的估计数
