Ancestry Composition Basics

posted this on December 05, 2012 02:27 PM

Ancestry Composition is our update to the Ancestry Painting feature that tells you what percent of your DNA comes from each of 31 populations worldwide. The analysis includes DNA you received from all of your ancestors, on both sides of your family. The results reflect where your ancestors lived 500 years ago, before the advent of intercontinental travel.

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 if you have a parent genotyped and linked in the Family Tree.
  • By changing the confidence threshold, you can see 3 levels of interpretation for your results, from Speculative to Conservative.
