Admixture Calculator

MDLP K27

**MDLP K27 — ModernAncient Global Admixture** A high-resolution admixture calculator that decomposes your autosomal DNA into proportions across 25 global reference populations (Africa, Eurasia, Oceania, Americas). Designed for worldwide users, it combines modern and ancient proxies to highlight recent vs deep ancestry, reveal regional affinities, and provide historical context while noting model-based limitations.

About This Calculator

**MDLP K27 — ModernAncient Global Admixture Calculator** This calculator analyzes autosomal genetic data to estimate ancestry proportions by comparing your DNA to a curated set of 25 global reference populations spanning both modern and deep-time proxies. It is designed to reveal how much of your genome resembles regional and ancient genetic clusters — from East African Nilotic and Central-African hunter-gatherer lineages to Eurasian, Oceanian and Native American ancestries. Who it's for - Individuals with multinational or complex family histories - Enthusiasts exploring deep and recent ancestry - Researchers and community geneticists seeking fine-scale continental and subcontinental signals What you learn - Quantitative ancestry proportions attributed to 25 reference groups (examples: Nilotic-Omotic, Bantu, Bushmen, Caucasian–Near Eastern, North-European–Baltic, Gedrosia-Caucasian, Ancestral-South-Indian, Kalash, Ancestral-Yayoi, Papuan-Australian, North/South Amerindian, Arabic, Austronesian) - Relative contributions reflecting recent admixture versus deeper population structure (ModernAncient framework) - Geographic and historical context for detected components that suggest migrations, founder events, or regional continuity Genetic and historical context MDLP K27 integrates broad, globally distributed reference populations to span major human lineages and underrepresented groups. By including both modern and ancestral proxies, it helps distinguish recent gene flow from older, persistent genetic signatures tied to ancient migrations and population splits. Why this calculator is valuable - Global scope: tuned for worldwide users and mixed ancestries - Resolution: highlights regional and subcontinental signals often missed by coarse models - Contextual interpretation: couples numeric results with historical and population insights Limitations This is a model-based estimate using proxies; results depend on reference sampling and SNP overlap.

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

How It Works

Your DNA is compared to 27 reference populations
Modern & Ancient 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 & Ancient populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
