DNA doesn’t lie and it certainly won’t protect the feelings of racists. A bigoted father-in-law learned his lesson when his grandkid shared surprising DNA test results.
According to Tiffany Roy, the forensic DNA expert we consulted, “DNA testing is like any other human endeavor. It’s not without error and bias. It’s not a perfect science so it really just depends on several different factors how that might impact a person’s ethnicity. The accuracy is dependent on the knowledge, training and experience of each individual analyst handling the evidence. Some are very good. Too many are subpar.
He also stated, “The tests themselves are quite accurate in terms of the information that they get from a person’s DNA. We should be less confident about our understanding of the populations that that information is compared to — ‘Congolese. for instance, may not mean the same thing today that it meant 200 years ago and may not have ever been that well-defined a population to begin with.”comes from their parents, grandparents, and all the ancestors before them.
Genetic testing might reveal way more than we bargained for. In this case, it helped put a racist in his place and gave the poster a sense of relief. The post got 2.8k upvotes and comments, with people applauding the author’s plan and execution. Have you ever taken a DNA test or known someone who received shocking genetic test results? Spill the tea in the comments; don’t leave us hanging!
