World and American Breakdown K28 — Modern global admixture calculator
This calculator analyzes genome-wide patterns of genetic ancestry by comparing a tested genotype to a curated panel of 28 reference populations from across the globe, with dense representation of Indigenous American groups. It quantifies proportional ancestry from sources such as Cree, Raramuri, Pima, Zapoteco, Mixteco, Nahua, Maya, Quechua, Karitiana, Surui, multiple European clusters, African regions, Middle East, South and East Asia, Southeast Asia, Oceania and others to produce a refined breakdown relevant to modern populations.
Who it’s for
- Genealogy enthusiasts, adoptees, and family history researchers
- Population geneticists and students seeking comparative context
- Anyone curious about complex ancestry in the Americas and worldwide
What you’ll learn
- Estimated proportions from 28 reference groups, highlighting fine-scale Indigenous American structure and global contributions
- Signals of colonial-era admixture (European, African, and Middle Eastern inputs) and earlier migrations (Asian and Oceanian) where present
- Geographic and historical context to help interpret mixed ancestries
Why this matters
- Many global calculators aggregate Indigenous American ancestry into a single category; K28 resolves multiple autochthonous groups to reveal regional Indigenous substructure
- Useful for distinguishing nearby European clusters (Northern, Eastern, Southwest, Western) and African regional contributions
- Helps translate genetic estimates into historical narratives: migration corridors, colonization events, and recent admixture patterns
This tool prioritizes transparency: reference populations are named and geographically anchored, and results should be interpreted as statistical estimates rather than definitive labels. Use alongside family history, archival records, and regional knowledge for the most meaningful insights.

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 28 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 28 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
