Twins get some 'mystifying' results when they put 5 DNA ancestry kits to the test
Found on CBC on Saturday, 19 January 2019
Last spring, Marketplace host Charlsie Agro and her twin sister, Carly, bought home kits from AncestryDNA, MyHeritage, 23andMe, FamilyTreeDNA and Living DNA, and mailed samples of their DNA to each company for analysis.
Despite having virtually identical DNA, the twins did not receive matching results from any of the companies.
When asked why the twins didn't get the same results given the fact their DNA is so similar, 23andMe told Marketplace in an email that even those minor variations can lead its algorithm to assign slightly different ancestry estimates.
So in other words, the tests are a complete waste of time and money. Not to mention that customers hand over their DNA samples to a profit-focused company who fails to deliver anything substantial.
