reference populations

When it comes to calculating 23andMe customers’ Ancestry Composition results, details are invariably what matter most: more specificity, more interactivity, more opportunities to draw meaning about how we are all...

23andMe has added new and more diverse reference populations, allowing customers with African and East Asian ancestry to see a more detailed breakdown of their Ancestry Composition. The update was made possible thanks to the contributions of 23andMe customers, as well as new sources of publicly available data such as the 1000 Genomes Project, and from the company's own African Genetics Project.

23andMe expands by five fold the number of regions used its interactive Ancestry Composition report, vastly increasing your ability to peer deeper into your genetic origins, connect you to different populations around the world, and learn more about yourself.

With a new genotyping chip and additional data, 23andMe has revved up its Ancestry Composition feature, giving customers more precision in learning about their geographic origins of their ancestry.
