More African Genomes are Being Sequenced to Increase the Diversity of Genomic Data

About 30 million or so people have had their DNA sequenced in the 20 years after the first human genome was decoded. Yet, only of these genomes are of people of African ancestry.

Over 30 million additional people have had their DNA sequenced in the 20 years since the first human genome was completed. Nonetheless, less than 2% of these genomes are from those of African ancestry. This exposes a huge vacuum in our understanding of human genetic variation and evolution, and it also suggests that there is room for far greater use of…
