How many conjoined twins are there in the world?
It is estimated that conjoined twins occur in about 1 in every 200,000 live births, which means there are likely several hundred pairs of conjoined twins in the world at any given time. However, exact numbers are difficult to determine due to the rarity of the condition and privacy concerns.
Are twins exactly the same age or is one of them older by just a few seconds?
Twins usually have the same birthdays but one is always older. Sometimes they are born minutes or even hours apart.
Can identical twins be of different sexes?
They can be. While identical twins always have to be the same gender, fraternal twins usually are not. However this is not always the case. Identical twins occur because they inhabit the same egg. Fraternal twins because two eggs were fertilized at the same time. So fraternal twins could be the same gender, but usually they are of the opposite gender.
Why are twins called Siamese twins?
Chang and Eng Bunker (no relation to Archie) were the first pair to survive to adulthood. They were male and they hailed from Siam, hence the name. It is a congenital anomaly and is not linked to any specific ethnic group. The Hilton sisters appeared to be partly at least Italo-American. Conjoined twins is the preferred term. Siam (now Thailand) rejected the term as racist and asked other countries to not use that term.
What is the difference between dizygotic twins and monozygotic twins?
Dizygotic twins develop from two separate ova fertilized by different sperm at roughly the same time, they are also called fraternal twins. Monozygotic twins develop from one zygote that splits apart producing genetically identical zygotes; also called identical twins.
What is conjoined twins?
At one time called "Siamese Twins", these are twins that, prior to birth, their bodies are permanently joined together in some manner.
How many conjoined twins are there in the world?
It is estimated that conjoined twins occur in about 1 in every 200,000 live births, which means there are likely several hundred pairs of conjoined twins in the world at any given time. However, exact numbers are difficult to determine due to the rarity of the condition and privacy concerns.
Are there fewer conjoined twins today than in the past?
The incidence of conjoined twins has remained relatively stable over time, occurring in about 1 in every 200,000 live births. Advances in medical technology and prenatal care may lead to improved outcomes for conjoined twins, but they do not significantly reduce the occurrence rate. Factors such as maternal age and genetic predispositions can influence the likelihood of conjoining, but overall, the prevalence has not shown a marked decrease.

What is the differences between identical twins and fraternal twins?
Identical twins arise from a single fertilized egg that for some reason split itself in two. Identical twins have exactly the same genetic make-up.Fraternal twins arise from two separate eggs. Sometimes both of a woman's ovaries will produce an egg cell at the same time. Each of these is fertilized by a separate sperm cell (of which there are always plenty) so they have different genetic make-up. They may share the same womb and be born at the same time but are no more closely related than true brothers.
