There have been 70 instances of parents and children competing at the same Olympics, but three-time medalist Nino Salukvadze and her 18-year-old son, Tsotne Machavariani, of Georgia, will be the only mother-son combination.
"I am very happy as the representative of the Georgian shooting federation but a million times happier as a mother that my son managed to do this," Salukvadze, 47, told the Associated Press.
According to Olympic historian Bill Mallon, fathers and sons have competed together at the Olympics on 56 different occasions, fathers and daughters 12 times and mothers and daughters only twice.

Salukvadze is heading to her eighth Olympics this summer – only the second woman in history to do so, according to Mallon.
This will be Machavariani's first Olympics – he snagged a qualifying spot on the Georgian team after shooting a personal best in the 10-meter air pistol at the European championships in February, reports AP.
"At the Olympics I will be representing my mother, my country and myself," he told the news outlet.
The mother and son train together, but Machavariani says his mother does not put pressure on him to follow in her footsteps.
"She does not demand any results from me," he told AP.
