Admixture Calculator

MDLP K18b

MDLP K18b is a 17-component admixture calculator that decomposes your DNA into ancient-informed regional ancestries. Suited for worldwide users—from curious genealogists to researchers—it highlights proportions of components like ANI, ASI, CHG, Northeuropean, East and Southeast Asian, Siberian, Papuan/Melanesian, Paleoafrican and Subsaharian to reveal deep population affinities and migratory signals. Model-based and globally comprehensive.

About This Calculator

MDLP K18b is an ancestry admixture calculator that estimates proportional ancestry using a 17-component reference panel tuned to ancient and deep population structure. Designed for global users — hobbyists, genealogists, population geneticists, and anyone curious about biogeographic roots — it translates your genetic data into percentages that reflect affinities to components such as ANI (Ancestral North Indian), ASI (Ancestral South Indian), CHG (Caucasus Hunter‑Gatherer), Northeuropean, SouthEuropean, NearEast, various East and Southeast Asian groups (EA, NorthEastAsian, SEA), Siberian, Uralic, Arctic, Amerindian, Melanesian, Papuan, Paleoafrican and Subsaharian ancestries. What it analyzes: MDLP K18b compares your genotype to modeled ancestral clusters representing deep and regionally distinct lineages. The calculator quantifies mixtures of ancient and modern-informative components to reveal likely population affinities and broad migratory signals rather than pinpoint recent family-level relationships. Insights you can gain: results show the proportional contribution of each component to your genome, highlighting major regional ancestries and smaller, legacy signals (for example CHG-related Caucasus influence, ANI/ASI structure in South Asia, or Papuan/Melanesian signatures in Oceania). Users can use these outputs to explore hypotheses about migration, admixture events, and continental ancestry composition across time. Historical/genetic context: MDLP K18b bridges modern genomes with ancient-informed clusters. Components like CHG, ANI, and ASI reflect deep prehistoric population structure revealed by ancient DNA studies; Paleoafrican and Subsaharian categories acknowledge Africa’s deep diversity. The inclusion of Arctic, Siberian and Uralic components captures northern Eurasian dynamics. Why it’s valuable: the calculator offers broad, interpretable ancestry decomposition with global coverage. It’s a practical tool for comparative exploration, educational use,

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

How It Works

Your DNA is compared to 18 reference populations
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
Ancient populations are used as references
Percentages indicate relative genetic contribution
Results are estimates based on available reference data
