Description

Marques Modern Europe and Middle East K19 is a high-resolution admixture calculator designed to decompose a modern individual’s genome into 19 geographically informed ancestry components spanning Europe, the Middle East, North Africa, and adjacent regions. Using allele-frequency profiles derived from carefully chosen reference populations, this calculator estimates proportional ancestry from clusters such as Scandinavia, Greek & Balkans, Volga & Oural, North_East_Africa, Middle_East, Sardinia, Italian substructure, and several pan-European and extra-European groups. It is optimized for users whose ancestry traces to Europe, the Mediterranean rim, the Middle East and nearby areas, including genealogists, hobbyist geneticists, regional historians, and researchers seeking a clear snapshot of recent population structure. Insights you can gain include a mapped breakdown of recent ancestral contributions (percentages), identification of primary regional affinities, and detection of minor components that may reflect historical migrations or recent admixture events—for example Steppe-related, Mediterranean farmer-related, North African, or Near Eastern signals. The calculator places these results in accessible genetic context, explaining how modern population structure reflects millennia of movement: prehistoric farming expansions, Bronze Age steppe dispersals, classical-era mobility across the Mediterranean and Balkans, and more recent historical gene flow across the Middle East and North Africa. Why use this calculator: it offers a balanced, interpretable set of 19 components that maximizes geographic resolution without overfitting, making it practical for personal ancestry exploration and comparative research. Results are presented with clear caveats about reference set limitations, statistical uncertainty, and the difference between genetic affinity and cultural or national identity. Whether you are tracing family roots, comparing regional ancestries, or contextualizi

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

How It Works

Key Points

Your DNA is compared to 19 reference populations
Modern populations are used as references
Results show your genetic similarity to these populations

Understanding Your Results

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

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