My first DNA test I took was with 23andme. This was in 2010 so I was probably among the “early adopters” 🙂 Throughout the years there have been several features available on 23andme. Which enabled me to learn many valuable things about my own origins as well as those of the wider Afro-Diaspora. But only with 23andme’s latest update in 2018/2019 did I get the feeling I was really zooming into something substantial & meaningful!

In this section I will provide a brief overview of some of the useful features on 23andme to help Trace African Roots. I aim to expand my discussion of these various features eventually. More detailed discussion can be seen by clicking on the subsections which already have a link below. Or also via the main drop-down menu (below the banner).

Survey of the African breakdown on 23andme
Since 23andme’s update in 2018 I have been collecting updated Ancestry Composition results in a spreadsheet in order to conduct a survey of the African origins being reported by 23andme for both Africans and Afro-descended nationalities. At this moment of writing it contains at least 850 results for 45 nationalities. Among which 200 are for African Americans and nearly 100 for Cape Verdeans. In order to enable easier comparison with the results for native Africans I have recalculated the original African percentages so that they add up to 100%. Whenever needed. In other words the scores mentioned in my speadsheet represent fractions of a person’s total African ancestry and not fractions of their entire ancestry. It is a scaled breakdown. Below is a link to the spreadsheet which contains all the results. Besides a tab for the main statistics there are several other tabs on the bottom of the sheet where the individual results can be found, sorted according to nationality.
These are the links to the blog posts I have written so far in an attempt to analyze and illuminate the African breakdown for each group. More are to follow:
