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.
There are two types of twins; identical and non-identical. Identical or monozygotic twins are formed when one egg is fertilized by one sperm which then divides into two separate embryos. Each shares exactly the same genetic components and identical genetic structures. Identical twins also share a placenta.
