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.
The important difference between identical and fraternal twins is the number of fertilized eggs involved. Identical twins come from a single fertilized egg. Fraternal twins come from two different ones. Identical twins happen when a single embryo splits in two soon after fertilization. This is why identical twins have identical DNA.
