Admixture Calculator

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
