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.

O que é a análise de mistura genética?
A análise de mistura genética estima a semelhança genética comparando o seu DNA com populações de referência de diferentes partes do mundo. Os componentes do modelo representam essas referências e dependem dos dados e pressupostos utilizados.
Esta calculadora utiliza 15 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
- Tu DNA se compara con 15 poblaciones de referencia
- Modern se utilizan como referencias genéticas
- Os resultados mostram a sua semelhança genética com estas populações
- A diversidade do painel de referência influencia as estimativas
Como interpretar seus resultados
Os resultados mostram percentagens de similaridade genética com estas populações de referência. Tenha presente estes pontos:
- Os resultados reflectem a semelhança genética, não ascendência directa demonstrada
- Modern se utilizan como referencias
- As percentagens indicam contribuições relativas no modelo
- Os resultados são estimativas baseadas nos dados de referência disponíveis
