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.

نبذة عن الحاسبة
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

ما تحليل التركيب الجيني؟
يقارن تحليل التركيب الجيني حمضك النووي ببيانات مجموعات سكانية مرجعية من أنحاء العالم. ويقدّر مدى التشابه مع المكوّنات المرجعية التي يتألف منها النموذج.
تستخدم الحاسبة 12 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
