...borne him five children. "There is not an individual in the neighborhood of Charlottesville who does not believe the story," Callender wrote, "and not a few who know it." Jefferson never confirmed or denied Callender's story. But the likely truth of the Hemings affair was dramatically bolstered by DNA tests published in 1998, which indicated that a Jefferson male had sired at least one of Hemings' children...
...some 700 descendants of Jefferson, had held its annual reunion without a horde of reporters and photographers in attendance--or the extended family members who had triggered the controversy. The once obscure association, which administers the graveyard at Monticello, got caught in a media storm in 1998, after a DNA study confirmed to the satisfaction of many that a male member of Jefferson's family had fathered at least one child with a mulatto slave named Sally Hemings (she gave birth to at least six, and possibly seven, children in all). If that Jefferson was the third President, as many...
...what began as an extended-family reunion has disintegrated into a bitter family feud between Jefferson's white family and his black one. For the first time since the DNA results came out, not a single Hemings attended the association's annual reunion this past May. "Nobody wants to be where they aren't wanted. The environment felt stuffy and very formal," says Shannon Lanier, a Hemings who works as a TV production assistant in New York City and co-authored a book about the family called Jefferson's Children: The Story of One American Family. Instead, last year...
...would be easy to chalk up the entire family squabble to racism. After all, a primary reason the Hemings liaison was widely doubted before the DNA results were published was that testimony from former black slaves was dismissed by white historians as unreliable gossip. Blacks were not the only ones who supported the story, however. Numerous white journalists in Jefferson's time reported the story and believed it to be true. Jefferson's fellow Founding Father John Adams, who had seen Hemings' beauty firsthand (she was known as "Dashing Sally"), also seemed to believe that Jefferson had had an affair...
...more toxic side effects of anticancer drugs, while others either lack such agents or have genes that produce the opposite effect, making them more sensitive to the drug's adverse effects. Researchers at MGH, for example, found that changes in the gene coding for an enzyme involved in DNA repair can mean the difference between breast-cancer patients who can tolerate chemotherapy and those with a twofold greater chance of experiencing a toxic reaction...
