The affair of the president

In 1998, probably the most famous DNA analysis case to date was solved with a Y-chromosome test: Was Thomas Jefferson the father of the children of his slave Sally Hemmings? The DNA of five descendants of Thomas Jefferson's paternal uncle, Field Jefferson, were analyzed in this case to examine the Y-chromosome profile of this family. Direct paternal descendants of Sally Hemmings' son served as a comparison. John Weeks Jefferson, the only living descendant of Eston Hemmings, confirmed with his Y chromosome that both families belonged to the same paternal line.
Thomas Jefferson belonged to haplogroup T in the paternal line.
