Marques Modern Europe and Middle East K19
Marques Modern Europe and Middle East K19 (Modern) — A K=19 autosomal admixture calculator that compares your DNA to 19 modern reference populations across Europe, the Middle East, North Africa and beyond. Ideal for genealogy enthusiasts and researchers, it reveals fine regional ancestry proportions, migration signals, and minor admixture while noting limitations tied to reference panels and modern-population inference.

Marques Modern Europe and Middle East K19 — Modern era admixture calculator
This calculator estimates autosomal ancestry proportions by comparing your genetic profile to 19 modern reference populations spanning Europe, the Middle East, North Africa, Sub‑Saharan Africa and beyond. Using a K=19 model, it teases apart fine regional affinities that are especially relevant for people with European and neighboring-Middle‑Eastern backgrounds.
What it analyzes
- Genome-wide autosomal markers to compute proportional similarity to each reference cluster.
- Relative contributions from populations such as Italy, Greek & Balkans, Scandinavia, Baltic, Volga & Oural, Middle East, North Africa, North East Africa, and others.
Who this is for
- Genealogy and family-history enthusiasts with roots in Europe, the Caucasus, or the Middle East.
- Population genetics students and researchers needing an accessible modern-reference admixture profile.
- Anyone curious about recent ancestry and regional genetic signals (not medical or trait prediction).
What insights you can gain
- Proportional breakdown of likely regional ancestry across 19 modern population clusters.
- Signals of historical migrations (e.g., steppe/Volga influences, Mediterranean vs Northern European components).
- Detection of minor admixture from distant regions (e.g., Sub‑Saharan, South/Central Asia, or North Africa) that reflect past gene flow.
Context and limitations
- The model uses contemporary reference populations; inferred components reflect similarity to those groups today, not direct one-to-one ancient ethnicity.
- Percentages are model-based estimates influenced by reference choice and marker density; they indicate affinity, not definitive origin.
Why it's valuable
- Provides a nuanced, regionally informed portrait of recent ancestry across Europe and neighboring regions.
- Helps users contextualize family history, compare profiles, and generate hypotheses for deeper genealogical or academic f

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 19 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
كيف يعمل التحليل؟
- يقارن التحليل حمضك النووي بعدد 19 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
