Global Ancestry K9
Global Ancestry K9 — Ancient Admixture Overview
Quickly estimate ancient ancestry proportions across nine broad source populations (West African, Southeast Asian, South Asian, Pacific, European, Pygmy, WANA, Siberian, Native American). Designed for researchers and enthusiasts, K9 reveals deep-time affinities, highlights major prehistoric migrations, and provides an intuitive baseline for interpreting ancient and modern genomes. Model-based and best used with complementary evidence.

Global Ancestry K9 — Ancient Era Admixture Calculator
Global Ancestry K9 analyzes genome-wide autosomal patterns to estimate ancient ancestral contributions using a nine-population reference panel. Built around deep-time signals, this tool measures proportional affinity to nine broad ancient clusters: West African, Southeast Asian, South Asian, Pacific, European, Pygmy, West Asian–North African (WANA), Siberian, and Native American.
Who it's for:
- Genetic genealogists, archaeogeneticists, and history enthusiasts wanting clearer views of prehistoric ancestry
- Researchers comparing modern or ancient samples to broad continental and subcontinental source groups
- Anyone curious about deep ancestral components beyond recent genealogical pedigrees
What you gain:
- A proportional breakdown of inferred ancient ancestry across nine modeled sources
- Visual summaries (bar charts/clines) that highlight dominant and minor components
- Contextual interpretation that links proportions to major prehistoric migrations, such as Out-of-Africa dispersals, Holocene expansions, and peopling of the Americas and Oceania
Historical and genetic context: Global Ancestry K9 emphasizes macro-scale population structure relevant to the Ancient era. The nine reference groups represent long-standing regional lineages and demographic processes—hunter-gatherer substrata (Pygmy, Siberian), agricultural expansions (West Asian–North African, South Asian), maritime dispersals (Pacific, Southeast Asian), and continental clines (European, West African, Native American).
Why it matters:
- Translates complex allele-frequency patterns into intuitive ancestry components tied to archaeological and population-history narratives
- Helps formulate and test hypotheses about ancient admixture and migration routes
- Complements high-resolution studies by offering a clear, comparative baseline across major prehistoric source 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 9 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
كيف يعمل التحليل؟
- يقارن التحليل حمضك النووي بعدد 9 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
