Jeff Yang writes an entertaining piece at SFGate.com about the current genetealogy craze. His friend Grace had her DNA tested as part of a course in physical anthropology.
"My professor asked us to do research about our ethnic origins, and I told him, 'I can go back a couple of generations in my family, back to my great grandparents, and I'm pretty much sure they're all Chinese,'" she says. "And he challenged me -- he said: 'Don't just take that for granted. Prove it. Do a DNA marker test and show me.'
"My report came back and pretty much said in big letters, 'YOU ARE CHINESE,'" says Grace. "I told my family during a holiday family meal, and everyone just laughed themselves silly. My sister fell off her chair, saying, 'You paid a hundred bucks to learn that? Are you sure that Web site wasn't Sucker.com?'" [Link]
