When DNA testing is used to claim racial purity

In 2018, an internet discussion thread asked participants to post their DNA test results to prove their «pedigree and genetic quality». The proposal, framed within a racial purity discourse, revealed how commercial ancestry tests can be co-opted by pseudoscientific ideologies.

One participant shared his breakdown: 65% Eastern Europe, 20% northwestern European, 10% Balkan, 4.8% Finnish and 0.2% Inuit. Another showed 59% Iberian Peninsula, 27% Basque and 15% Italian. Far from encouraging reflection, the exchange descended into insults and accusations of not daring to show the results.

The background of the debate reveals a paradox: modern genetics has dismantled the biological concept of race, yet some sectors use it in an attempt to validate racial hierarchies. Companies like MyHeritage offer these tests without filtering their use, and the scientific community warns that ancestry percentages are statistical estimates, not absolute truth.

The lingering question is whether the commercialization of genetics is helping to perpetuate racial myths instead of banishing them. The thread, though limited in scope, exemplifies how technology can serve both knowledge and the reinforcement of prejudice.
