Find out more about the DNA ancestry company aiming to increase its appeal across a wider range of ethnic groups. They're attempting to correct the racial bias in DNA databases, so customers get a fuller story of who they are.

Genetic studies have primarily been done nearly exclusively in European populations to date and DNA databases are four to one skewed in favour of European DNA.

But diversity drives are unearthing genetic treasure. Slavery scrubbed the family histories of generations. Genetics is helping African Americans, for one, piece together their stolen stories.

In this episode David Reid hears the story of Jamila Zheng who found her ancestral home and relatives she didn't know existed after taking a DNA test. We also hear from Dr Steven Micheletti, Population Geneticist at 23andMe and Dr Anjali Shastri, Senior Research Programme Manager at 23andMe about the diversity drive at their company.
