Today in News: Man's X Chromosome Dominates Olympic Women's Swimming

---

RIO DE JANEIRO — All the world's abuzz with the utter Olympic dominance of 19-year-old swimmer, David Ledecky's daughter. The one-time recipient of a sex-determining X chromosome, David Ledecky's daughter has taken home five medals, including four golds, at the 2016 Olympic Games.

Born in Washington, DC to parents Mr. and Mrs. David Ledecky, David Ledecky's daughter burst onto the international swimming scene at the 2012 London Olympics with an unlikely win in the women's 800-meter freestyle.

Since then, David Ledecky's daughter's ascendency has included consistent world record-setting and a spot on the Time 100 list. But it was truly the Rio De Janeiro Games that cemented David Ledecky's daughter's legacy.

In the women's 800 meter freestyle, David Ledecky's daughter finished 11 seconds ahead of the nearest competitor, who, by the end of the race, wasn't even in the frame following the leader. The performance was unlike any other by a man's daughter at the Games, and the world is better and more inspired for having seen what a man's X chromosome can do.
