Conclusion
The correction of the Sierra Leone mtDNA data set led to a decrease in the number of African-American matches to single ethnic groups.
Supporting Evidence
- The database size was reduced from 3725 to 3717 sequences.
- The number of African-American matches to single ethnic groups dropped from 16 to 9.
- This change represented just 5% of the African American sequences compared.
Takeaway
They found that African American DNA often matches DNA from different African groups, but after fixing a mistake in their data, they found fewer matches.
Methodology
The researchers reconstructed their database using a corrected Sierra Leone mtDNA data set and reanalyzed the data.
Limitations
The study was limited by the initial mislabeling of the Sierra Leone mtDNA sequences.
