Admixture Calculator

World and Jewish Breakdown K28

**World and Jewish Breakdown K28** — A modern-era admixture calculator optimized for Jewish individuals. It compares your DNA to 25 reference populations (11 Jewish subgroups plus regional groups like East-Med, Caucasus, North-African and West-European) to produce a fine-grained percentage breakdown. Ideal for genealogy, community research, and exploring historical admixture with clear, interpretable results.

About This Calculator

**World and Jewish Breakdown K28 — Modern-era Admixture Analyzer** This calculator estimates the proportional ancestry of an individual against a 28-cluster model (K28) tuned for modern populations, with special emphasis on Jewish communities. It compares your DNA to 25 reference populations — including 11 Jewish subgroups (e.g., Ashkenazi, Sephardic, Yemenite, Ethiopian-Jewish) and 14 regional groups (Anatolian, East-Med, Caucasus, West-European, North-African, South-Asian, West-Asian, etc.). What it analyzes - Genome-wide autosomal variation to produce percentage affinities to each reference population - Fine-scale differences among Jewish groups and neighboring regional sources - Signals consistent with historical migrations, conversions, trade routes and local admixture Who it's designed for - Jewish individuals curious about internal community structure and regional admixture - Genealogists, family historians and community researchers investigating recent ancestry - Researchers seeking a modern-era, Jewish-aware reference framework Insights you can gain - Quantified shares from distinct Jewish communities (e.g., Ashkenazi vs. Sephardic) and non-Jewish regional sources - Detection of North-African, East-Med, Caucasus or South-Asian components that reflect historical contacts - Context for endogamy, founder effects and admixture timing when combined with other tools Historical and genetic context The Jewish diaspora spans millennia of migrations, conversions and local admixture. By contrasting multiple Jewish subgroups with surrounding populations, K28 highlights both shared Levantine heritage and community-specific inputs (e.g., North-African, Iberian, Central-Asian or Ethiopian signals) shaped by regional history. Why this calculator is valuable - Tailored reference panel: greater resolution for Jewish-related ancestry than broad global models - Actionable outputs: clear percentage breakdowns suitable for personal reports or downstream analysis - Educatio

28 Reference Populations

Jewish Populations:

Ashkenazi-Jewish: Jewish communities originating from Central and Eastern Europe.

Indian-Jewish: Jews from India, including groups like Bene Israel and Cochin Jews.
Iraqi-Jewish: Jews from Iraq, one of the oldest Jewish communities outside Israel.
Moroccan-Jewish: Jews from Morocco, reflecting many centuries of coexistence with Berber and Arab cultures.
Romanian-Jewish: Jews from Romania, with communities in regions such as Moldavia and Wallachia.
Sephardic-Jewish: Jews originally from the Iberian Peninsula who settled in Southern Europe and North Africa.
Uzbek-Jewish: Jews in Uzbekistan, including both Bukharan and Ashkenazi communities.
Yemenite-Jewish: Jews from Yemen, known for their unique liturgical traditions and cultural practices.

Continental Groupings:

Understanding Admixture Analysis

Learn how admixture calculators work and how to interpret your results

What is Admixture Analysis?

Admixture analysis is a method used to estimate your genetic ancestry by comparing your DNA to reference populations from around the world. Think of it as creating a recipe of your genetic makeup, where the ingredients are different ancestral populations.

This calculator uses 28 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 28 reference populations
Modern populations are used as genetic references
Results show your genetic similarity to these populations
More accurate with a diverse reference panel

Understanding Your Results

Your results will show percentages of genetic similarity to these reference populations. Remember these important points:

Results reflect genetic similarity, not direct ancestry
Modern populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
