She shouldn't have done this

WASHINGTON — Senator Elizabeth Warren has released a DNA test that provides "strong evidence'' she had a Native American in her family tree dating back 6 to 10 generations, an unprecedented move by one of the top possible contenders for the 2020 Democratic nomination for president.
Warren, whose claims to Native American blood have been mocked by President Trump and other Republicans, provided the test results to the Globe on Sunday in an effort to defuse questions about her ancestry that have persisted for years. She planned an elaborate rollout Monday of the results as she aimed for widespread attention.
The inherent imprecision of the six-page DNA analysis could provide fodder for Warren's critics. If her great-great-great-grandmother was Native American, that puts her at 1/32nd American Indian. But the report includes the possibility that she's just 1/1024th Native American if the ancestor is 10 generations back.

Correction: Due to a math error, a story about Elizabeth Warren misstated the ancestry percentage of a potential 10th generation relative. It should be 1/1,024.
