Global Ancestry K39 with Jewish Populations
Global Ancestry K39 provides a fine-grained, world-wide autosomal admixture breakdown using 39 components mapped to 36 reference populations. Ideal for genealogy enthusiasts, students, and researchers, it reveals regional ancestry proportions (e.g., West African, Maghrebi, Iberian, South Asian, East Asian, Native American) and places your genome in historical migration context. Model-based and interpretive, not definitive.

Global Ancestry K39 — Modern global admixture calculator
Global Ancestry K39 analyzes autosomal genotype data to estimate proportional ancestry from a fine-grained set of global reference populations. Built for broad, world-wide sampling, this calculator decomposes an individual's genetic profile into 39 ancestry components (K=39) that map onto 36 carefully chosen reference populations spanning Africa, Europe, the Middle East, South and East Asia, Siberia, and the Americas.
What this calculator analyzes
- Genome-wide autosomal SNP variation to infer proportional ancestry contributions.
- Fine regional structure within continents (for example, multiple West African clusters, Iberian vs. Italian vs. Greek/Balkan, and distinct South and East Asian components).
- Relative affinities to historical and modern reference groups rather than explicit genealogical relationships.
Who it's designed for
- Genetic genealogy enthusiasts seeking detailed regional breakdowns.
- Researchers and students exploring population structure and admixture patterns.
- Anyone curious about multi-continental ancestry and historical migration signals.
Insights you can gain
- Percent-based ancestry composition across global regions (e.g., West African, Maghrebi, Ashkenazi, Han Chinese, Native American North vs. Central/South).
- Detection of mixed heritage from recent or older admixture events and identification of likely source regions.
- Comparative context: how your profile relates to reference groups such as Basque, Sardinian, Bedouin, Pakistani/Afghan, or Eastern Siberian natives.
Historical and genetic context
Human populations bear signatures of migrations, isolation, and contact: Out-of-Africa dispersals, regional hunter–gatherer substrata, agricultural expansions, trade networks, and recent colonial-era movements. K39 frames your genome against these layered histories using modern reference panels.
Why this calculator is valuable
- Provides a balanced, interpretable view of

ما تحليل التركيب الجيني؟
يقارن تحليل التركيب الجيني حمضك النووي ببيانات مجموعات سكانية مرجعية من أنحاء العالم. ويقدّر مدى التشابه مع المكوّنات المرجعية التي يتألف منها النموذج.
تستخدم الحاسبة 39 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
كيف يعمل التحليل؟
