‘It made me question my ancestry’: does DNA home testing really understand race?

Georgina Lawton and Daisy Ifama in The Guardian:

Last year, I did what 12 million people from all over the world have done and surrendered my spit to a home DNA-testing company. I hoped a MyHeritage test would bring me the peace I needed; my Irish mother had never been able to give me any information about my biological father. Raised by her and my white dad, I’d always longed for a country to attribute my blackness to, or for help answering the ubiquitous “Where are you from?” question. I’d spent years making up exotic-sounding combinations to justify my appearance (some days Jamaican-Spanish-Swedish; other days half Brazilian, or half Iranian). But, at 24, I was done with occupying a box of black ambiguity. Could I finally get a clear answer?

The results arrived by email on a summer’s day last year. I clicked on the “ethnicity estimate” link, which offers an analysis of DNA by country, my heart pounding as I scanned the digital map.

The test showed that my blackness comes from Nigeria; 43% of my DNA, in fact. Then there’s 1% from Kenya, and the rest from Great Britain and Ireland (55%), as well as eastern Europe (1%). I’d often been told I looked east African, or mixed with multiple countries, so I was surprised by what was nearly a 50:50 split.

I had no cultural knowledge of Nigeria; should I now start claiming it as my own? Did the results mean my very distant ancestors were Nigerian, or that my biological father was probably from there? Why did my features not resemble a typical west African? I felt more confused than ever.
