Mephisto Near East K19
Mephisto Near East K19 provides a high-resolution K=19 admixture breakdown using 19 modern reference populations. Tailored for global users with a focus on Near Eastern substructure, it quantifies contributions from Mesopotamia, Iran, Caucasus, Arabia, Mediterranean and global groups (Europe, Africa, South/East Asia, Siberia, Papuan). Ideal for genealogists, students and researchers seeking clear, comparative ancestry profiles.

Mephisto Near East K19 — Modern-era global admixture calculator
This calculator analyzes genome-wide ancestry proportions against a curated panel of 19 modern reference populations to reveal fine-scale Near Eastern and global admixture profiles. Using allele-frequency based modeling at K=19, Mephisto estimates the fractional contribution of distinct regional clusters to an individual's genetic makeup.
What it analyzes
- Proportions from 19 reference groups: Siberia, Balooch-Kalash, S_Asia, Europe, Papuan, Arabia, Mediterranean, N_Arabia, E_Asia, W_Africa, Bantu, SE_Asia, E_Africa, Iran, Egypt, S_Caucasus, N_Caucasus, Maghreb, Mesopotamia.
- Emphasis on discriminating Near Eastern substructure (Mesopotamia, Iran, Egypt, Arabian and Caucasus signals) while retaining global context (Sub-Saharan, South and East Asia, Oceania, Siberia, and Europe).
Who it's designed for
- Genealogy enthusiasts and community researchers seeking regional refinement within and around the Near East.
- Population geneticists and students needing a reproducible K=19 reference frame for comparisons.
- Anyone worldwide curious about how Near Eastern and adjacent ancestries contribute to their genome.
Insights you can gain
- Quantitative admixture breakdown highlighting Near Eastern clusters versus global components.
- Signals of historical migrations (e.g., Caucasus–Iranian influences, Mediterranean and North African admixture, South Asian or Siberian inputs).
- A clear visual and numeric baseline for hypothesis generation and comparison with archaeological or historical records.
Context & value
- Built from modern reference populations, Mephisto K19 offers high-resolution discrimination of regional Near Eastern ancestries in a global framework. It helps contextualize personal and population histories, guides more targeted downstream analyses, and serves as an educational bridge between genetics and 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 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
