Identical Twins occur when a single egg is fertilized by a single sperm to form one zygote (monozygotic) but the zygote then divides into two separate embryos. The biological mechanisms that prompt the single fertilized egg to split in two remain a mystery. The two embryos develop into foetuses sharing the same womb.
The difference between fraternal and identical twins is that fraternal twins are two separate eggs fertilized by two separate sperm to form two separate embryos and then make two separate babies.Identical twins are formed when one fertilized egg divides into two separate embryos to make two babies.raternal, or dizygotic, twins happen when Mom releases two eggs (either at the same or different times during her cycle), and different sperm fertilize each egg. Fraternal twins share up to 50% of their genes, and are no more alike or different than any two siblings would be.
