Given the tests' speculative nature, it seems unlikely that colleges, governments and other institutions will embrace them. But that has not stopped many test-takers from adopting new DNA-based ethnicities — and a sense of entitlement to the privileges typically reserved for them.
Prospective employees with white skin are using the tests to apply as minority candidates, while some with black skin are citing their European ancestry in claiming inheritance rights.
One Christian is using the test to claim Jewish genetic ancestry and to demand Israeli citizenship, and Americans of every shade are staking a DNA claim to Indian scholarships, health services and casino money.
"This is not just somebody's desire to go find out whether their grandfather is Polish," said Troy Duster, a sociologist at New York University who has studied the social impact of the tests. "It's about access to money and power."
Ashley Klett's younger sister marked the "Asian" box on her college applications this year, after the elder Ms. Klett, 20, took a DNA test that said she was 2 percent East Asian and 98 percent European.
Whether it mattered they do not know, but she did get into the college of her choice.
"And they gave her a scholarship," Ashley said.
Mr. Haedrich, a nursing home director who was raised a Christian, found through a DNA ancestry test that he bears a genetic signature commonly found among Jews. He says his European ancestors may have hidden their faith for fear of persecution.
Rabbis, too, have disavowed the claim: "DNA, schmeeNA," Mr. Haedrich, 44, said the rabbi at a local synagogue in Los Angeles told him when he called to discuss it.
