LM Genetics K15
LM Genetics K15 — 15-way global admixture snapshot
A modern, interpretable K=15 calculator that breaks your autosomal DNA into 15 regional components (e.g., West-African, Siberian, Kalash, Papuan, Red-Sea). Designed for users worldwide, it reveals proportional affinities, signals of deep versus recent admixture, and historical connections—an ideal starting point for genealogy and population-history exploration.

LM Genetics K15 — Modern 15-way Admixture Calculator
LM Genetics K15 decomposes a person's autosomal DNA into 15 reference components representing broad and regional ancestries from across the globe. This calculator compares your genotype to allele-frequency profiles for the following proxies: West-African, Siberian, South-Indian, Ne-Asian, Kalash, Papuan, Paleo-African, Samoyedic, NE-Euro, SE-Asian, Tibeto-Burmese, SW-Euro, Caucasian, Amerindian, and Red-Sea.
What this calculator analyzes
- Relative contributions of 15 reference populations to your autosomal ancestry.
- Signals of deep (ancient) versus more recent regional admixture.
- Patterns that reflect migration events, isolation, and population structure.
Who it's designed for
- Individuals worldwide curious about multi-regional ancestry beyond continental labels.
- Genetic genealogy enthusiasts seeking moderate-resolution components.
- Researchers and students who want an interpretable, reference-based K=15 snapshot.
Insights you can gain
- Proportional ancestry estimates that highlight affinities to well-defined regional proxies (e.g., Kalash-like, NE-Euro, Red-Sea).
- Clues about historical contacts (e.g., Siberian input into Native American ancestors, Papuan signals in Oceanian-admixed profiles).
- A basis for comparing results across calculators or for triaging populations for more detailed study.
Context and caveats
- Reference components are model-based proxies, not literal “pure” peoples. They summarize allele-frequency patterns useful for comparative interpretation.
- Admixture proportions depend on the reference dataset, marker density, and recent drift. Small percentages can reflect deep shared ancestry or noise.
Why this calculator is valuable
- Provides a balanced middle ground between coarse continental splits and highly granular panels.
- Helps users form testable hypotheses about population history and personal ancestry in a globally inclusive framework.

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 15 من المجموعات السكانية المرجعية المختارة بعناية لاستكشاف أوجه التشابه الجيني.
كيف يعمل التحليل؟
- يقارن التحليل حمضك النووي بعدد 15 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
