In the case of both identical and fraternal twins, the placenta and chorion may be shared, but it is very rare for both the placenta and the amniotic sac to be shared. b. In the case of fraternal twins, each fetus usually has its own placenta, chorion, and amniotic sac. Identical twins may each have their own placenta, chorion, and amniotic sac.
