Eurogenes JTest
Eurogenes JTest — Focused European admixture analysis
A region-centered autosomal calculator for people with modern European roots. Eurogenes JTest compares your DNA to 14 reference clusters (from SOUTH_BALTIC to SIBERIAN and AFRICAN components) to quantify Baltic, Mediterranean, Steppe, Ashkenazi and neighboring signals. Ideal for genealogists and enthusiasts seeking a clear, contextual breakdown of European ancestry while acknowledging probabilistic limits.

About This Calculator
Eurogenes JTest — Precision admixture for modern Europeans
Eurogenes JTest is a focused genetic admixture calculator designed to analyze the complex ancestry of people with recent roots in Europe. Using a calibrated set of 14 reference populations, the calculator estimates proportional ancestry across regional and cross-continental components to reveal patterns of kinship, migration, and regional affinity.
What this calculator analyzes
- Genome-wide autosomal ancestry proportions against 14 reference clusters: SOUTH_BALTIC, EAST_EURO, NORTH-CENTRAL_EURO, ATLANTIC, WEST_MED, ASHKENAZIM, EAST_MED, WEST_ASIAN, MIDDLE_EASTERN, SOUTH_ASIAN, EAST_AFRICAN, WEST_AFRICAN, EAST_ASIAN, SIBERIAN.
- Relative affinities to northern, southern, eastern and peripheral European profiles, and low-level signals from adjacent regions (Middle East, West Asia, South Asia, Africa, Siberia).
Who it's designed for
- People with recent European ancestry seeking a refined regional breakdown.
- Genealogists, population genetics enthusiasts, and researchers looking for intuitive admixture summaries.
Insights you can gain
- Quantified regional proportions (e.g., Baltic vs. West Mediterranean) and detection of distinctive signatures such as Ashkenazi or Middle Eastern contributions.
- Clues to historical migrations: Neolithic farmer, Steppe, Mediterranean and later movements reflected in modern genomes.
- Identification of minor transcontinental inputs (African, South Asian, East Asian, Siberian) that inform recent or ancient contacts.
Historical and genetic context Europe’s genetic landscape is a tapestry shaped by Paleolithic settlers, Neolithic farmers from the Near East, Bronze Age Steppe expansions, and millennia of trade and migration. Eurogenes JTest frames your genetic data within this long-term context by comparing your DNA to modern-derived regional clusters, making visible the echoes of those movements.
Why this calculator is valuable
- High-resolution, region-focused results
Reference Populations
The populations used as genetic references in this calculator
14 Reference Populations
EUROPE
- SOUTH_BALTIC: Peaks in the Baltic area (Lithuanians).
- EAST_EURO: Peaks in Eastern Europe (Udmurts, North Russians, Erzyas, and Komis).
- NORTH-CENTRAL_EURO: Peaks in Scandinavia (Norwegians, Danish, Swedish, English).
- ATLANTIC: Peaks in Western European Atlantic regions (French Basques, Scottish, Irish, Orcadians).
- WEST_MED: Peaks in Sardinia (Sardinians).
- ASHKENAZIM: Peaks in the Ashkenazim. NOTE: Almost everyone in the world scores some Ashkenazim percentage; this is not an indicator of any Ashkenazim heritage. A score of 15% or more can be a clear indicator of any recent Jewish ancestry.
MIDDLE EAST AND ASIA
- EAST_MED: Peaks in the Levant (Druzes, Samaritans).
- WEST_ASIAN: Peaks in West Asia (Georgians, Lezgins, Kalash, Armenians).
- MIDDLE_EASTERN: Peaks in the Middle East (Bedouin, Ethiopian, Somalis).
- SOUTH_ASIAN: Peaks in South Asia (Gujarati, Bangladeshi).
AFRICA
- EAST_AFRICAN: Peaks in East Africa (Masai).
- WEST_AFRICAN: Peaks in West Africa (Yoruba).
ASIA
- EAST_ASIAN: Peaks in East Asia (Chinese, Northern Hans, Koreans, Japanese).
SIBERIA
- SIBERIAN: Peaks in Siberia (Nganassans, Koryaks, Chukchi).
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 14 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.
How It Works
- Your DNA is compared to 14 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
