MDLP World 22
MDLP World 22 — Global Modern+Ancient Admixture
A 22-component admixture model that blends modern and ancient reference proxies to reveal fine-scale global ancestry. Ideal for genealogists, researchers and curious users, it quantifies regional and prehistoric signals (Neolithic, Mesolithic, Siberian, Austronesian, Amerindian, African, Melanesian) to illuminate migration history and complex admixture patterns.

MDLP World 22 — Modern+Ancient Admixture Model
MDLP World 22 analyzes autosomal DNA using a 22-source reference panel that mixes modern and ancient proxies to reveal fine-scale global ancestry. The model quantifies how much of your genome matches diverse ancestral components such as Atlantic Mediterranean Neolithic, North-European-Mesolithic, Indo-Iranian, Austronesian, Melanesian, Pygmy, and multiple Amerindian, Siberian and African lineages.
Who this is for:
- Genetic genealogists and ancestry enthusiasts seeking detailed regional breakdowns
- Researchers and students comparing modern/ancient signals
- Anyone curious about migration histories and deep regional affinities
What you learn:
- Percent contributions from 22 reference populations spanning Eurasia, Africa, Oceania and the Americas
- Signals of ancient demography (e.g., Neolithic farmer, Mesolithic hunter-gatherer, Paleo-Siberian and Austronesian inputs)
- Modern admixture patterns from recent migrations and long-range contacts
Historical and genetic context: The MDLP World 22 model combines modern population samples with proxies for ancient groups to provide a bridge between recent population structure and deeper prehistory. It highlights processes such as the spread of farming across the Mediterranean, Siberian and Beringian links to the Americas, Austronesian expansion into Island Southeast Asia and Oceania, and sub-Saharan and Pygmy diversity in Africa.
Why it’s valuable:
- High-resolution, globally focused panel with both modern and ancient components
- Helps disentangle overlapping signals (e.g., distinguishing Atlantic Mediterranean Neolithic from North-European-Mesolithic)
- Useful as a comparative tool alongside other calculators and archaeological records
Caveats: Like all admixture models, results are model-dependent and approximate. Use MDLP World 22 as an informative lens — not a definitive pedigree — to explore your genetic ties to global human history.

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 22 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
كيف يعمل التحليل؟
- يقارن التحليل حمضك النووي بعدد 22 من المجموعات السكانية المرجعية
- يستخدم التحليل مجموعات سكانية مرجعية من الفترات المعروضة.
- توضّح النتائج مدى التشابه الجيني مع هذه المجموعات
- تؤثر ملاءمة المراجع وتنوّعها في جودة المقارنة
فهم النتائج
تعرض النتائج نسبًا مقدّرة ضمن نموذج المقارنة بالمجموعات المرجعية. ضع النقاط التالية في الاعتبار:
- تعبّر النتائج عن التشابه الجيني ولا تثبت النسب المباشر
- تعتمد المقارنة على المجموعات المرجعية المدرجة في الحاسبة.
- تبيّن النسب الوزن النسبي لكل مكوّن في النموذج
- النتائج تقديرات تستند إلى البيانات المرجعية المتاحة
