Genghis Khan: 16 Million Descendants?! The Shocking Truth! Geneticists have recently studied the Y chromosomes which are passed down from father to son and they have estimated that 0.5% of the Earth's male population which equals to around 16 million males are direct descendants from Genghis Khan This means that he would have had to have had hundreds of children and we know that his son Tashi had 40 sons and his grandson Kublai Khan had 22 legitimate sons #genghiskhan #genetics #population #mongolianempire #genghis #history #worldhistory
