No, there can be a delay in the death. The most famous set, Chang and Eng Bunker, died three 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.
How is a fraternal twin different than other twins?
Fraternal means "brother-like." Identical twins result from a single fertilzed egg dividing into two separate embryos so the twins share all DNA. Fraternal twins result from two different eggs being fertilized by two different sperm at the same time. The babies are then born at the same time, but only share 25%of their DNA with each other, which is the same amount that siblings born at different times share. The word fraternal used in social organizations, like "the fraternal order of"...refers to the thought that the members are like brothers to each other. Modern french uses the word frere to mean brother.
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 the genetic difference between identical and non identical twins?
Identical twins are formed by the separation of the same embryo containing same genetic coding. thus the the twins are identical as formed from the same embryo. But this is not the case in the non-identical twins as they are formed from the individual embro each having different genetic coding.
Are identical twins the same in their genes?
Nope. Research has shown that DNA in twins is different, especially in copy number varitations, which refers to when a gene exists in multiple copies, or a set of letters in the DNA is actually missing. These variations are suspected to lead to increased defense against some infections, or vulnerability to others. http://www.nytimes.com/2008/03/11/health/11real.htmlTheir genes are very similar.Because the two embryos are the result of a single egg/sperm combination, they have the same genetic origins. They have the same DNA. however, they don't have the same finger printsAlmost! While the sequence begins identical, epigenetics (environmental type factors) appear to cause them to change over time.
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 do you get twins on babydow?

What do you call three children born at the same time?
when two babies are born at the same time are callled twins!
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.
Do twins have to be born on the same day?
twins just have to develop in the same womb at the same period of time. When they are born has nothing to do with it.
What are twins born at the same time but do not look alike called?
Fraternal twins.
Can twins be born a year appart?
No, twins are born from the same pregnancy, and at the same time give or take an hour or so.
How many calves are usually born at the same time to a cow?
Always one. I've never heard of two calves being born at the same time; if there were twins, it's always one after the other, as the cow's pelvis is only wide enough to allow one calf through at a time.
What do you call babies born at the same time?
twins
If you have twins will they hit puberty around the same time?
It is possible,but we are all different,even twins and triplets.
Ted and ed are brother they have the same mother and father but are born on the same day same time same hospital but are not twins how is that possible?
Ted and Ed are two of a set of triplets born together, with a third sibling. This means they share the same birthday, time of birth, and parents, but are not twins.
What are seven babies born at the same time with the same mother called?
Twins Also, they are called identical twins if they come from the same egg
