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.

参考人口
计算器中用作遗传参考的种群
15 Reference Populations
- West-African: Composed mainly of ethnic groups from the western part of Sub-Saharan Africa.
- Siberian: Indigenous populations of Siberia, including various ethnic groups native to Northern Asia.
- South-Indian: Populations from the southern part of the Indian subcontinent, with Dravidian cultural and linguistic roots.

- Papuan: Indigenous people from Papua New Guinea and surrounding islands in Oceania.
- Paleo-African: Ancient lineages originating from Africa, possibly representing early African human diversity.
- Samoyedic: A subgroup of the Uralic peoples residing in the Urals and northwestern Siberia.
- NE-Euro: Northeast European populations, including ethnic groups from countries like Estonia and Finland.
- SE-Asian: Ethnic groups from Southeast Asia, such as those from Thailand, Vietnam, and Indonesia.
- Tibeto-Burmese: Populations speaking Tibeto-Burman languages, found across regions like Tibet, Nepal, and Myanmar.
- SW-Euro: Southwest European populations, including groups from the Iberian Peninsula and parts of France.
- Caucasian: Ethnic groups from the Caucasus region between the Black Sea and the Caspian Sea.
- Amerindian: Indigenous peoples from North, Central, and South America.
- Red-Sea: Populations surrounding the Red Sea, including groups from parts of the Arabian Peninsula and Northeast Africa.

什么是“混合分析”?
混合分析是用来通过将你的DNA与来自世界各地的参考人群进行比较来估计你的基因祖先的一种方法。 把它看作是创造了你的基因化妆的食谱, 即成分是不同的祖先种群。
此计算器使用 15 仔细选择 modern 作为参考,可以详细分解您的遗传遗产。
如何运作
- 将您的 DNA 与 15 个参考人群进行比较
- 以 Modern 人群作为遗传参考
- 结果显示你的基因与这些种群相似
- 使用不同的参考面板更准确
了解你的成果
您的研究结果将显示与这些参考人群的遗传相似性的百分比。请记住这些要点:
- 结果反映了遗传相似性,而不是直接祖先
- Modern populations are used as references
- 表明相对遗传贡献的百分比
- 结果是根据现有参考数据作出的估计数
