Hyy here is your answer-
To form identical or monozygotic twins, one fertilised egg (ovum) splits and develops into two babies with exactly the same genetic information. To formfraternal or dizygotic twins, two eggs (ova) are fertilised by two sperm and producetwo genetically unique children.

The causes of identical twinning are much vaguer. No clear explanation is offered by science. Data about monozygotic twins in populations indicates that the rate generally remains stable across populations and time periods. No specific theory has been confirmed as to why a fertilized egg splits and develops into two embryos.
As technology improves, scientists are getting closer to finding answers. One 2007 study used specialized computer software to capture photos of embryos developing and found that the embryo basically collapses, splitting the progenitor cells in half and dividing them into two sets of genetic material that form as two separate fetuses.
While the discovery was important, it still didn’t pinpoint the reason for the split or explain exactly why identical twins happen. No genetic link has been identified. Some theories have been proposed but not confirmed. These include:
An enzyme in sperm
A mutation in the cells of the blastocyst
Age of the egg after ovulation
