MDLP K12b
MDLP K12b is a global admixture calculator (ModernAncient era) that estimates ancestry across 12 reference components—ANI, ASI, Northeuropean, Caucasian, Volga Ural, African HG, NEA, Siberian, Arctic, SEA, Papuan, and Amerindian. It’s designed for researchers, genealogists, and ancestry enthusiasts seeking a nuanced view of regional and deep ancestral affinities worldwide. Results offer probabilistic, comparative insights into migration and population history.

关于此计算器
MDLP K12b is a global admixture calculator designed to estimate the proportional ancestry of an individual across twelve informative population components. It blends modern and deep-time reference signals (ModernAncient era) to reveal both recent regional ancestry and older population structure. The model reports contributions from: ANI (Ancestral North Indian), ASI (Ancestral South Indian), Northeuropean, Caucasian, Volga Ural, African HG (Hunter‑Gatherer), NEA (Northeast Asian), Siberian, Arctic, SEA (Southeast Asian), Papuan, and Amerindian.
Who it’s for: the calculator suits researchers, genealogists, informed hobbyists, and anyone curious about global genetic roots. Because it uses worldwide reference populations, it is particularly useful for people with complex or mixed heritage, including those with South Asian, Eurasian, Indigenous American, Siberian, Oceanian, or African lineages.
What it analyzes and the insights you can gain: MDLP K12b assesses genome-wide allele frequencies and assigns proportions to each reference cluster. Results help you understand continental and subcontinental ancestry patterns (for example, the ANI/ASI cline characteristic of South Asia), detect Northeuropean vs. Caucasian/Volga-Ural influences in Eurasia, and identify northern Asian signatures (NEA, Siberian, Arctic). Presence of SEA, Papuan, or Amerindian components highlights Southeast Asian, Oceanian, or Native American connections; African HG flags deep African hunter-gatherer affinities.
Context and limitations: The model simplifies continuous genetic variation into discrete components — a useful shorthand but not an exact genealogy. Proportions are probabilistic estimates dependent on the reference set and statistical method. Interpret results as a guide to ancestral affinities and migration history rather than definitive proofs of origin.
Value proposition: MDLP K12b offers a balanced, interpretable snapshot of global ancestry with attention to both regional nuance (AN

12 Reference Populations
South Asian Continent
- ANI (Ancestral North Indian): A distinct ancestral component found within modern South Asian populations.
- ASI (Ancestral South Indian): A specific ancestral component distinct from Ancestral North Indian (ANI) within modern South Asian populations.
European Continent
- Northeuropean: Genetic ancestry linked to populations of Scandinavia, the Baltic states, and neighboring regions.
- Caucasian: Genetic heritage associated with populations originating from the Caucasus Mountains region, known for its ethnic and linguistic diversity.
- Volga Ural: Ancestry found in populations around Russia's Volga River and Ural Mountains, exhibiting a mixture of European and Finno-Ugric influences.
African Continent
- African HG (Hunter-Gatherer): Ancient African lineages stemming from populations with traditional hunter-gatherer lifestyles.
Asian Continent
- NEA (Northeast Asian): Ancestry prevalent in populations of China, Korea, Japan, and parts of Siberia.
- Siberian: Genetic ancestry found in the indigenous communities inhabiting the vast Siberian region of Russia.
- Arctic: Ancestry linked to indigenous peoples who have adapted to the extreme climates of the far northern latitudes.
- SEA (Southeast Asian): Genetic ancestry originating from the diverse populations of countries like Vietnam, Thailand, and Indonesia.
Oceanian Continent
- Papuan: Describes the genetic heritage of populations native to Papua New Guinea and neighboring Melanesian regions.
Americas
- Amerindian: Indigenous ancestry spanning diverse populations throughout both North and South America.

什么是“混合分析”?
混合分析是用来通过将你的DNA与来自世界各地的参考人群进行比较来估计你的基因祖先的一种方法。 把它看作是创造了你的基因化妆的食谱, 即成分是不同的祖先种群。
此计算器使用 12 仔细选择 现代与古代 作为参考,可以详细分解您的遗传遗产。
如何运作
- 将您的 DNA 与 12 个参考人群进行比较
