Sobre esta calculadora
Modern World K40 is a curated genetic admixture calculator that decomposes an individual’s autosomal DNA into proportions across 40 thoughtfully selected, modern reference populations. Designed for a global audience—genealogists, adoptees, family-history enthusiasts, citizen scientists, and researchers—it transforms raw genotype data into an accessible, interpretable map of regional ancestry. The calculator compares your SNP profile to a dense panel of reference groups that represent major modern population clusters: multiple African lineages (hunter‑gatherers, Bantu, West Africa, Nilotic, Horn of Africa, North Africa), a fine-grained European set (Iberia, British Isles, Scandinavia, Italy, Balkans, Anatolia, Caucasus, Central and Eastern Europe, Basque, Sardinia and others), diverse Asian components (China, Northern China/Korea/Japan, East and Central Siberia, South and Central Asia, Persia, Tibet, Southeast Asia, Austronesian, Vietnam‑Dai), as well as representative Levantine, Arabian, North Levant/Mesopotamia, Central/Eastern Mediterranean groups, the Americas and Oceania.
What it analyzes: genome‑wide allele‑frequency patterns to estimate proportional ancestry and regional affinities. What you learn: primary ancestral components, subtle admixture signals, likely multi‑regional heritage, and patterns consistent with major historical processes (for example, Bantu expansion across sub‑Saharan Africa, Neolithic farmer movements from Anatolia, steppe‑related gene flow into Europe, Austronesian dispersals, and the peopling of the Americas).
Why it’s valuable: Modern World K40 strikes a balance between resolution and interpretability—providing more detail than broad continental tests while using curated, modern reference clusters that reflect recent population structure. Results are presented with contextual notes and interpretation guidance so users can place genetic signals alongside documentary genealogy, haplogroup data, and known migration history. Important: ou

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 40 cuidadosamente seleccionadas modern populações como referências para descrever detalhadamente a semelhança genética.
Como funciona
