If they were not then they would not be called identical twins!
Heterozygous parents have the same odds of identical twins as the general population. Identical twins do not run in families and, therefore, twinning is not related to genetics. Comparisons among different ethnic groups rule out an ethnic cause-no difference. Only mother's age correlates with twinning: the older the mother, the greater the likelihood.
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
The fact that twins run in families is actually a myth. The odds of twins having twins is the same as a non-twin having twins. That is about 1 in 33.
Twins are not necessarily identical. They can be fraternal as well. Identical twins result when one fertilized egg splits in two. Fraternal twins result from two fertilized eggs.
I have an identical twin. For me it is no more likely that I will have twins than anyone else because identical twins are just flukes. If you are a non- identical twin and that is because your mother had two eggs, then you may have this too, and it is more likely you will have twins.
Identical twins make up about 0.2% of the world's population. This means that approximately 1 in every 250 births results in identical twins.
The odds are 75 percent.
From what i know, if your twins are identical then you have no increased chance of having twins a second time. If your twins are fraternal, you are twice as likely to have twins again because fraternal twins are the result of more than egg being released and that is a genetic trate.
Identical twins. Although horses sometimes have twins I'm not sure if they have identical twins.

Approximately 30 of twins are identical, also known as monozygotic twins.
Twins are identical because they come from the same egg.
Identical twins are formed from a single egg that splits into two. Fraternal twins are formed from two separate eggs that are both separately fertilized. So identical twins have identical DNA, and fraternal twins do not.
Identical twins are formed when one fertilized eggs splits. Non-identical twins are formed when two separate eggs are fertilized.
The same as when you had the first set of identical twins.
