Fraternal twins are developed from the fertilization of two separate eggs.

In most cases a woman releases one oocyte every month from alternate ovaries. Sometimes an oocyte is released from both ovaries at the same time both of which are fertilized by separate sperm. This results in the development of non-identical (fraternal) twins each having its own placenta for nourishment.
