What is the relationship between Venus and Serena Williams?

Serena and Venus Williams are the two most famous sisters in tennis. But the close-knit pair share 10 other siblings from their parents' other marriages and relationships. The Williams sisters' dad, Richard Williams, and their mom Oracene Price, met at a bus stop in 1979 and tied the knot in 1980, making Richard Williams the step-father of Price's three daughters, Yetunde Price, Lyndrea Price, and Isha Price, from her first marriage to Yusef A.K. Rasheed, according to the Los Angeles Times. Venus Williams, who was born in 1980, and Serena Williams, who was born in 1981, grew up in the same Compton, California, home as their sisters, according to the New York Times.
