Fraternal twins (dizygotic twins) are simply two fertilized eggs that are implanted in the uterus at the same time. Identical twins (monozygotic twins) is one fertilized egg that separates into two embryos. In most cases, identical twins share one placenta, but have separate amniotic sacs. In some cases, they have two placentas. In rare cases, they share both the placenta and the amniotic sac.
