MDLP K11a is a modern, world‑scale genetic admixture calculator that deconstructs an individual’s autosomal DNA into contributions from ten curated reference populations. Designed for researchers, genetic genealogists, ancestry enthusiasts, and anyone curious about biogeographical roots, this model highlights relative affinities to Siberian, Southeast Asian (SEA), Papuan, African, Amerindian, Indian, Onge (Andamanese), Asian Arctic, Northeuropean, and Westasian source groups. Using established population‑genetic clustering and allele‑frequency modeling approaches, MDLP K11a translates genome‑wide variation into interpretable proportional components. Results reveal the balance of ancient and recent ancestry signals in a person’s genome — for example, distinguishing South Asian and Onge‑related heritage from Westasian or Northeuropean inputs, or identifying traces of Papuan vs. Southeast Asian ancestry in Oceanian admixture. For global users, the calculator emphasizes broad continental and subcontinental patterns rather than fine-scale local ancestry. Historical and genetic context is embedded in the reference panel: Siberian and Asian Arctic components reflect northern Eurasian and circumpolar connections; SEA, Papuan and Onge components capture Southeast Asian and islander lineages; Indian and Westasian components mark South Asian and Near Eastern contributions; Northeuropean represents northern European ancestry; Amerindian and African capture Indigenous American and sub‑Saharan signals. These components mirror major migration episodes and long‑term population structure relevant to the modern era. Why MDLP K11a is valuable: it provides a clear, comparative framework to interpret mixed ancestry, supports hypothesis generation about migration and admixture, and helps place personal or study samples in a global genetic context. Users should note limitations: component labels are proxies for complex histories, resolution depends on the reference panel, and results d
