MDLP K18c
MDLP K18c is a global admixture calculator that breaks your autosomal DNA into 18 interpretable components (ANI, Dravidian, West/East European, Siberian clusters, EastAsian/NEA, Austroasiatic, Papuan, Polynesian, Amerindian, African/Eastafrican, and more). Suited to genealogists, researchers and curious users, it reveals regional affinities and signals from both recent and deep population history, offering fine-grained, global ancestry insight.

نبذة عن الحاسبة
MDLP K18c is a high-resolution admixture calculator built for modern and deep-time ancestry exploration. It decomposes an individual’s autosomal DNA into 18 reference components drawn from global populations — including ANI, Dravidian, SouthWestAsian, Caucasian, Westeuropean, Easteuropean, Volga_Ural, multiple Siberian clusters, Eastasian and NEA, Austroasiatic, Amerindian, Papuan, Polynesian, African and Eastafrican — to reveal both recent regional affinities and older population signals. Designed for a worldwide audience, it serves genealogists, adoptees, amateur ancestry enthusiasts, and population geneticists who want a balanced, interpretable portrait of genetic ancestry across Eurasia, Oceania, Africa, and the Americas.
MDLP K18c provides several practical insights: proportional ancestry breakdowns, detection of minority or unexpected components (for example trace Siberian or Papuan signals), and context for major historical demographic events such as Eurasian steppe movements, the spread of Austronesian and Austroasiatic languages, or the complex South Asian mixture between ANI and Dravidian-related ancestries. Because its references include both geographically focused modern clusters and components reflecting broader ancient clines, it helps bridge recent genealogical timeframes and deeper prehistoric population structure.
The calculator is valuable because of its global reference set and balanced granularity: 18 components provide more resolution than broad continental splits while remaining interpretable. Results can inform research hypotheses, guide targeted historical reading, or complement family history records. Users should note that admixture outputs are statistical estimates dependent on marker density and reference selection; they are best used as informative guides rather than definitive proof of precise genealogical relationships. MDLP K18c is a practical, transparent tool to explore where different strands of your ancestry likely originate and

18 مجموعة سكانية مرجعية
ANI (Ancestral North Indian)
- A prehistoric population of northern India, genetically related to West Eurasians, especially Caucasians, and distinct from the Ancestral South Indian (ASI) populations.
Continent: Africa
- African
- Refers broadly to populations from the African continent, encompassing diverse ethnic groups with significant genetic variation, including Sub-Saharan Africans, North Africans, and others.
- Eastafrican
- Populations from East Africa, including countries like Kenya, Ethiopia, and Tanzania, often associated with genetic markers related to Afro-Asiatic and Nilotic groups.
- African
Continent: Americas
- Amerindian
- Indigenous peoples of the Americas, descended from the first humans to migrate into the Americas from Siberia via the Bering land bridge.
- Amerindian
Continent: Asia
- Austroasiatic
- An ancient linguistic and ethnic group found mainly in Southeast Asia and parts of South Asia, including groups such as the Munda in India and the Mon-Khmer people in Southeast Asia.
- NEA (Northeast Asian)
- Populations from the northeastern regions of Asia, including areas like northern China, Korea, and parts of Siberia, with shared genetic characteristics.
- SouthWestasian
- Refers to populations from the southwestern part of Asia, including the Middle East and parts of the Arabian Peninsula, with deep historical links to early human civilizations.
- Austroasiatic
Caucasian
- Traditionally refers to populations from the Caucasus region and historically extended to a broad group including Europeans, West Asians, and some North African groups, though now the term is used more carefully.
Dravidian
- Refers to the indigenous peoples of southern India and parts of Sri Lanka, who speak Dravidian languages and are thought to have ancient roots in the Indian subcontinent.
Continent: Europe
- Easteuropean
- Populations from Eastern Europe, including Slavic, Baltic, and other ethnic groups, with genetic links to both Europe and West Eurasia.
- Westeuropean
- Populations from Western Europe, including groups such as the Celts, Germanic peoples, and others, with predominantly Caucasian ancestry and deep historical roots in the region.
- Easteuropean
Continent: Oceania
- Papuan
- Indigenous peoples of Papua New Guinea and nearby islands, with distinct genetic heritage from mainland Eurasian populations, related to early migrations from Africa.
- Polynesian
- Refers to the indigenous peoples of Polynesia, a subregion of Oceania, who are descended from the Austronesian-speaking Lapita culture and later oceanic migrations.
- Papuan
Continent: Siberia
- Northsiberian
- Indigenous populations from northern Siberia, often hunter-gatherer and reindeer herding groups with genetic links to both Eurasian and Native American populations.
- Siberian
- Populations native to Siberia, with great genetic diversity, including both ancient links to East Asia and some with connections to Native American ancestors.
- WestSiberian
- Populations from the western Siberian region, with a mix of European and Asian ancestry, often linked to ancient migrations and modern indigenous Siberian peoples.
- Volga_Ural
- Populations from the Volga and Ural regions of Russia, including Finno-Ugric ethnic groups with unique linguistic and genetic traits.
- Northsiberian
Eastasian
- Refers to populations from East Asia, including Chinese, Japanese, Koreans, and other related ethnic groups.

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 18 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
كيف يعمل التحليل؟
