Various types of chorionicity and amniosity (how the baby's sac looks) in monozygotic (one egg/identical) twins as a result of when the blastocyst or embryo splits. Monoamniotic twins are identical or semi-identical twins that share the same amniotic sac within their mother's uterus. [1] Monoamniotic twins are always monochorionic and are ...
Various types of chorionicity and amniosity (how the baby's sac looks) in monozygotic (identical) twins as a result of when the fertilized egg divides. Monochorionic twins are monozygotic (identical) twins that share the same placenta. If the placenta is shared by more than two twins (see multiple birth), these are monochorionic multiples ...

Approximately half are stillborn, and an additional one-third die within 24 hours. Most live births are female, with a ratio of 3:1. [5] [6] Two possible explanations of the cause of conjoined twins have been proposed. The one that is generally accepted is fission, in which the fertilized egg splits partially. [7]

Monochorionic twins are twins that share the same placenta. This occurs in 0.3% of all pregnancies, [3] and in 75% of monozygotic (identical) twins, when the split takes place on or after the third day after fertilization. [4] The remaining 25% of monozygous twins become dichorionic diamniotic. [4]
