Henry Louis Gates, Jr., on His Genome

From both his genome sequence and a paper record trail, Harvard University’s Henry Louis Gates, Jr., was able to delve into his ancestry, reports BusinessWeek. "It turns out that I'm descended on my mother's side from a white woman who was impregnated by a black slave, and on my father's side from an Irishman who conceived with a black woman named Jane Gates," he says, later adding: "I was searching for African roots, and they led to an African kingdom called the United Kingdom." Gates adds that he found nothing that worried him about his health.
