What are the odds of IVF identical twins?
1 in 250 live births is identical twins. IVF does not change the odds for identicals.
If atleast one person in your family has identical twins what are your chances of having identical twins and does someone in your family have to have had twins for you to be able to have twins?
The chance of having non-identical twins can run through genetics or be affected by the age of the mother. So the more people in your family tree that have twins, the more likely you are to have twins. However, twins can occur by chance, to someone who's family tree has no cases of twins, or from IVF. You do not have to have twins in your family line to give birth to twins. The chance…
yes, absolutely! Non-identical twins have a tendancy to be hereditary on your mother's side of the family. So for a female if your mother or mother's mother had non-identical twins there is a highler likelihood you might. Still, many twins don't have twins, and many people who aren't a twin do have twin. The increase in IVF has increase the number of multiple births in recent decades.
In the general population, the odds of having twins are about 3 in 100, or 3%. They seem to increase in relations to the mother's history, among other factors, but not the father's history. The odds of having identical twins are not affected by personal history of either parent. Identical twinning is a random event that occurs about 1 in 285, or about 0.35%.
There may be no connection to your odds of having twins and the fact that your uncle is a twin. It depends on whose side of the family the uncle is on. If the uncle is a fraternal twin on your mother's side, then your odds are slightly increased compared to the general population. If the uncle is an identical twin or on your father's side, your odds of having twins are the same as…
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.
Monozygotic (Identical or Maternal) twins are identical because they came from the same egg and were split after conception but before fetal development. Identical twins have nearly identical DNA, however, environmental factors may switch genes on and off, differences are more pronounced as the twins age. Dizygotic (Fraternal) twins are not identical. They are as different as any other siblings.
