Marques Modern World K40 — Modern-era Admixture Analyzer

This calculator analyzes your autosomal DNA against a high-resolution panel of 41 modern reference populations to estimate ancestry proportions across Eurasia, Africa, the Americas and Oceania. Built for the Modern era, K40 provides a granular breakdown of recent population structure by modeling up to 40 genetic components informed by contemporary groups.

Who it’s for

  • Genetic genealogy enthusiasts, adoptees and family historians seeking regional detail beyond continental labels
  • Researchers and students exploring modern population structure and recent admixture
  • Anyone with raw genotype data from common consumer platforms (upload your autosomal file) who wants a nuanced, interpretable ancestry profile

What you learn

  • Quantitative ancestry proportions tied to named reference populations (e.g., West_Africa, Levant_&_Arabia, Scandinavia, Austronesians)
  • Detection of minor and mixed ancestries that continental calculators can miss
  • Relative affinities that suggest historical contacts (e.g., Turkic-Central Asian influence, Austronesian reach, Siberian components in the Americas)

Historical and genetic context Human genetic diversity today reflects layers of migration and admixture: Out-of-Africa dispersals, Holocene farmer and pastoralist expansions, Bantu and Austronesian expansions, Silk Road exchanges, and colonial-era movements. K40 maps these modern patterns by comparing your genotype to populations sampled across Africa, Europe, Asia, the Americas and Oceania.

Why this calculator is valuable

  • More regional resolution than broad calculators, useful for resolving mixed heritage and regional ancestry signals
  • Transparent reference list (41 populations) that connects results to recognizable geographic and cultural regions
  • A practical tool for exploratory analysis, hypothesis generation, and complementing documentary genealogy

Note: Results are probabilistic and depend on t

Como interpretar a análise de mistura genética

Descubra como funcionam as calculadoras de mistura genética e como interpretar os resultados

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

  • Tu DNA se compara con 40 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
