Conjoined twins sisters, also recognized as Siamese twins, are conjoined identical twins at the uterus.
A very unusual consequence, the incident is assessed to happen from one in 49,000 childbirths, to one in 189,000 childbirths, with a relatively higher occurrence in Africa, and Southwest Asia.
Virtually half of them are stillborn, and another one-third of them die between 24 hours. The majority of births that survive are female, with a probability of 3 to 1.
Two opposing theories occur to illustrate how conjoined twins originate. The more commonly recognized concept is fission, whereby the fertilized egg partially divides.
The other concept, which is fusion, is no more believed to be an origin of conjoined twins, the fertilized egg totally divides, but the stem cells searches for the same stem cells, and weave the twins jointly.
Conjoined twins have a single fetal membrane, placenta, and innermost membranous sac.
Even though these traits are not restricted to conjoined twins, because there are a few monozygotic, but there are non-conjoined twins that likewise share these patterns in utero.
The twin sisters are joined from their waist down to the pelvis region, where the backbones meet. They both have 2 arms, but each of them controls 1 leg, the right leg is controlled by Carmen, and the left leg by Lupita.
