Ancestry Composition Basics

Ancestry Composition tells you what percent of your DNA comes from each of 31 populations worldwide. This analysis includes DNA you received from all of your recent ancestors, on both sides of your family. The results reflect where your ancestors lived before the widespread migrations of the past few hundred years.

Here are some tips for getting started with Ancestry Composition:

  • You can zoom in to view the regional and sub-regional results by clicking on the zoom controls that appear next to the views dropdown, or by clicking on the population labels.

  • There are 3 different views to explore in the feature; Map View, Chromosome View, and Split View. Map View and Chromosome View are available to all customers, while Split View is available only for members that have one or more genotyped parents with whom they are sharing genomes.
