It’s to me sort of curious that there has been no specific discussion of chromosomes. Do any male descendants of Sally Hemmings have the Jefferson Y chromosome, or are we strictly talking X chromosome here, since the Carr nephews keep coming up? Or, is it an X chromosome attributable to Randolph Jefferson? Innuendoes don’t prove a thing. Proof of paternity is a scientific endeavor, is it not, or are we dealing yet again with political science?
They are talking about the Jefferson Y chromosome appearing in a male line of descent from Sally Hemings (her son’s son’s son, etc) Whether it was Thomas Jefferson, president to be, who contributed that Y chromosome can not be proved or disproved - but a Jefferson was the father of that line.
