Walajahi explained to the crowd that DTC ancestry kits fall short on accuracy because they only offer a probability toward a certain ancestry. So, a test that claims an individual has Native American ancestry, could be wrong.

…Ancestry kits can’t determine Native American identity. Community relationships, traditions, and shared experiences are more important aspects of identity.

…“Using a genetic test to lay claim to any connection to the Cherokee Nation or any tribal nation…is inappropriate and wrong,” said Cherokee Nation Secretary of State Chuck Hoskin Jr. in a public statement. “It makes a mockery out of DNA tests and its legitimate uses while also dishonoring legitimate tribal governments and their citizens.”

Sovereign tribal nations determine their requirements for membership. A genetic ancestry test is rarely involved. A history of traditions, passing down crafts and skills, and a sense of cultural continuity set the baseline for tribal membership.

…With no regulatory body to oversee their methods, Hull hopes the companies come together to create a set of standards on their own ensuring that they use consistent language to help the public understand how to interpret genetic information.
