Admixture Calculator

Mephisto Grand K12 Modern

**Mephisto Grand K12 Modern** provides a clear 12-way breakdown of modern ancestry by comparing your genotype to twelve contemporary reference populations (Papuan, Yakut, Caucasus, W_Africa, E_Asia, Kalash, NW_Europe, Arabia, Mozabite, S_Asia, Brahui-Baloochi, Mediterranean). Ideal for global users, genealogists, and educators seeking an interpretable snapshot of recent admixture and population affinities. Results are probabilistic and reflect modern population structure.

About This Calculator

**Mephisto Grand K12 Modern** is a 12-way genetic admixture calculator designed to provide a clear, modern snapshot of ancestry by comparing an individual's genotype to twelve contemporary reference populations. Using allele-frequency contrasts across a broad genomic panel, it estimates proportional ancestry contributions and highlights major biogeographic affinities. What it analyzes - Genome-wide ancestry proportions across 12 reference groups: **Papuan, Yakut, Caucasus, W_Africa (West Africa), E_Asia (East Asia), Kalash, NW_Europe, Arabia, Mozabite, S_Asia, Brahui-Baloochi, Mediterranean**. - Modern population structure and recent admixture signals rather than ancient haplotype reconstruction. Who it's designed for - Global users seeking a high-resolution overview of modern ancestry. - Genetic genealogy enthusiasts, educators, and researchers exploring population structure and recent admixture patterns. Insights you can gain - Relative ancestry percentages tied to geographically and historically meaningful reference groups. - Signals of recent admixture (e.g., Eurasian clines, African components, South and East Asian inputs, Oceanian ancestry). - How modern population structure in your genome aligns with known migration corridors and regional isolates (e.g., Kalash, Yakut, Mozabite). Historical and genetic context This K12 model frames contemporary genetic diversity shaped by major movements such as Out-of-Africa dispersals, Eurasian steppe and Neolithic farmer expansions, regional drift and isolation, African and Oceanian histories, and more recent mobility across Arabia and the Mediterranean. Because the panel uses present-day reference populations, it emphasizes recent population structure and admixture. Why this calculator is valuable - Delivers an interpretable 12-way breakdown that balances resolution and clarity. - Useful for comparative analysis, educational visualization, and personal ancestry exploration. Important caveats - Results are prob

Reference Populations

The populations used as genetic references in this calculator

12 Reference Populations

Papuan: Indigenous people of Papua New Guinea and surrounding islands, known for their diverse cultures and languages.
Yakut: Indigenous people of Siberia, primarily living in the Sakha Republic (Yakutia), part of the Russian Federation.
Caucasus: Populations from the Caucasus region, an area situated between the Black and Caspian Seas, culturally and ethnically diverse with influences from Europe and Asia.
W_Africa (West Africa): Ethnically diverse region of West Africa, known for its rich cultural heritage and historical significance in the African continent.
E_Asia (East Asia): Encompasses countries like China, Japan, and Korea, characterized by distinct languages, cultures, and historical developments.
Kalash: An ethnic group residing in the Chitral District of Pakistan, known for their unique cultural practices and polytheistic beliefs.
NW_Europe (Northwest Europe): Covers countries like the UK, Ireland, and Scandinavia, encompassing a variety of cultures and languages within a European context.
Arabia: Refers to populations of the Arabian Peninsula, known for the desert landscape and rich history that includes the rise of Islam.
Mozabite: Berber ethnic group residing in the M'zab region of Algeria, known for their distinct cultural traditions within the Maghreb.
S_Asia (South Asia): Includes countries like India, Pakistan, and Bangladesh, characterized by a rich diversity of languages, religions, and cultures.
Brahui-Baloochi: Ethnic groups primarily found in Pakistan, with Brahui speaking Dravidian languages and Baloochi speaking an Iranian language.
Mediterranean: Refers to populations living around the Mediterranean Sea, an area known for its historical cross-cultural interactions.

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 12 carefully selected modern populations as references, allowing for a detailed breakdown of your genetic heritage.

How It Works

Your DNA is compared to 12 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
