Fraternal Twins vs. Identical Twins. Fraternal twins are âdizygotic,â meaning that they developed from two different eggs fertilized by two different sperm cells, while identical twins are âmonozygoticâ i.e., they developed from a single fertilized egg that split.
Monoamniotic twins are identical twins that share the same amniotic sac within their motherâs uterus. Monoamniotic twins are always identical, always monochorionic and are usually termed Monoamniotic-Monochorionic (MoMo) twins. They also share the placenta, but have two separate umbilical cords. Monoamniotic twins develop when an embryo does not split until after formation of the amniotic sac, at about 9-13 days after fertilization.
