WHY are Siamese twins born?

Siamese twins is one of the phenomena of multiple pregnancy, resulting in the birth of babies who share some organs or body parts.

This pathology is caused by the fact that the fertilized cell develops initially as a single embryo, and then “decides” to split into two parts, while some organs are already formed. Unlike the appearance of normal twins, the division of the embryo occurs an order of magnitude later, not at the cell level, as it should be, but at the level of the embryo.

Siamese twins have a very low chance of survival, from 5 to 25% of the total number of births, and girls are the most common among them.
