Tolan Recent Ancestors V2 — Modern-era Global Admixture Analyzer
Tolan Recent Ancestors V2 estimates the recent genetic contributions to an individual's ancestry by comparing their autosomal DNA to a curated panel of 32 modern reference populations. It is built to detect and quantify regional ancestry that most likely arrived within the last few generations, offering a clear, interpretable breakdown of where your recent ancestors most likely originated.
What this calculator analyzes
- Autosomal admixture proportions against 32 contemporary reference groups representing Africa, Europe, Asia, the Americas, and Oceania.
- Relative contribution of populations such as East_Africa, North_Africa, Sub-Sahara, Amerindian, Arabia, China, India, Iran&Assyria, Levant, Turkey, Balkans, Scandinavia, Spain, Oceania and more.
- Patterns consistent with recent migration, mixed heritage, and multi-continental ancestry.
Who it is for
- Genealogy enthusiasts and adoptees seeking clues about grandparents and great‑grandparents.
- Researchers and students exploring recent population structure and migration signals.
- Anyone curious about the regional mix of their recent ancestors across the modern world.
Insights you can gain
- Percent estimates for each reference region to help pinpoint recent ancestral origins.
- Identification of likely multi-regional ancestry across Europe, Africa, Asia, the Americas, and Oceania.
- Context for ambiguous family stories, immigrant origins, and recent admixture events.
Historical and genetic context
Human populations have continually mixed during recent centuries due to trade, colonization, and migration. This calculator emphasizes those recent signals rather than deep, ancient splits—making it especially useful for reconstructing family history in the modern era.
Why Tolan Recent Ancestors V2 is valuable
- High-resolution, globally diverse reference panel optimized to detect recent admixture.
- Actionable, easy-to-interpret results th

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 32 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 32 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
