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.
Identical twins have exactly the same DNA. They will be the same sex and they are more likely to look like each other. Fraternal or non-identical twins develop from two separate fertilized eggs. Non-identical twins will share on average half of their DNA, similar to the percentage of DNA shared by two siblings who are not twins. Fraternal twins can be the same or different genders.
