In Star Plus serial, it is shown that Krishna is exchanged with daughter of Nand and Yashoda. When Kans tried to kill the exchanged daughter, she transforms into some other character and disappears. The character's face was same as Subhadra actor in the serial. So possibly they want to show it was Subhadra.
So based on that, Yashoda should be mother of Subhadra?
But when I searched and read on Wikipedia, found out that Rohini was mother of Subhadra.
What's the truth?
