Have there been any recorded instances of genetically identical human siblings other than identical twins?
Identical (N>2)-tuplets, also known as higher order multiples, are extremely rare. The chance of having identical (N>2)-tuplets is estimated to be about 1 in 100 million births.
(N>2)-tuplets occur when a single fertilized egg splits into multiple embryos. This is known as monozygotic twinning. The exact cause of this phenomenon is not fully understood, but it is thought to be a random occurrence and not influenced by genetics or environmental factors.
No, there is no known genetic predisposition for (N>2)-tuplets. As mentioned before, the occurrence of (N>2)-tuplets is a random event and not influenced by genetics or family history.
Yes, it is possible for (N>2)-tuplets to be born at different times. This is known as asynchronous birth and can occur when the embryos split at different stages of development.
The birth of (N>2)-tuplets can be a high-risk pregnancy for the mother and babies. The mother may experience complications such as preterm labor, gestational diabetes, and high blood pressure. The babies may also be born prematurely and have a higher risk of health complications. It is important for the mother to receive specialized prenatal care to monitor the health of both the mother and babies.
