Quizplus · Accepted Answer

Identical twins, also known as monozygotic twins, are the result of a single fertilized egg that splits into two embryos. Therefore, they have the same genetic material. They may share a placenta, but there are cases where they have separate placentas. However, they always share the same amniotic sac and have a single umbilical cord.
