Twin – Wikipedia
Twins are two offspring produced by the same pregnancy. Twins can be either monozygotic (‘identical’), meaning that they develop from one zygote, which splits and forms two embryos, or dizygotic (‘non-identical’ or ‘fraternal’), meaning that each twin develops from a separate egg and each egg is fertilized by its own sperm cell. Since identical twins develop from one zygote, they will share …

About twins
Parents of twins have routinely been told that if their twins were born with the one placenta that they were identical. However in recent years there have been a few reports of twins who were told they were identical for precisely this reason – only to later find out that they are in fact non-identical.

Identical Twins: Information, Facts and Common Questions
They are monozygotic, which means they are formed when one egg is fertilized by one sperm but splits into two. They then develop into two embryos with genetic codes that are nearly identical. This usually happens during the earliest stage of fetal development when the fertilized egg is merely a cluster of cells that float down into the uterus. Although the process can be explained, the reasons why it happens remain a mystery.

Conjoined twins – Symptoms and causes – Mayo Clinic
Conjoined twins develop when an early embryo only partially separates to form two individuals. Although two babies develop from this embryo, they remain physically connected — most often at the chest, abdomen or pelvis. Conjoined twins may also share one or more internal body organs.

Univitelino Twins: Characteristics, How They Are Formed and Types …
These individuals are characterized by sharing their genetic makeup so they are of the same sex. They are very similar in their blood groups, fingerprints, and physical appearance. Although univitelline twins share 100% of their genes, differences caused by hereditary disorders can be detected in them, manifested in only one of them. These individuals may differ by somatic cell mutations, antibody composition, and degree of susceptibility to certain diseases.
