Are you more likely to have twins yourself if one of your parents is a twin?

There is a hereditary issue that can cause women to release two eggs during ovulation - and that hereditary trait COULD pass from the father to his DAUGHTERS.

You get your genetics from BOTH of your parents.  Your father CAN pass the genetic trait that causes the ovulation issues that releases two eggs.  That doesn't guarantee that you did get that trait and it doesn't guarantee you would release two eggs at every ovulation.  But, because there are twins in your direct family tree, your chances are just a little higher than someone who doesn't have that in their family tree.I DO know a man who has a twin sister.  The man and his twin sister NEVER had twins of their own.  So far, the man's daughter DID have a set of twins - and she was only 22 when she had them.  The sister has four children - no twins - so far, none of her daughters have had twins - but they are also not done having children either.There is nothing that you can do naturally to try to influence having twins.  

BTW - someone mentioned that twins "skip" a generation.  Your father is a twin.  As his daughter, YOU are the "skipped" generation and YOUR generation would be the ones that have the higher chance for twins based on that old belief that twins skip a generation.  In the family I know - that is exactly how it worked.  The twins did not have any twins - but so far, one of their children HAS had a set of twins.

No. Your dad's genes have no influence over your ovaries or eggs.

If there is a history on your MOTHER'S side of fraternal twins, then you MAY have inherited the tendency to release more than one egg duting ovulation.

Identical twins are a fluke. Everyone has the same chance at identical twins. They're not THAT rare; about one in every 250 births.

My sister has twins.  Our grandfather was a twin and her boyfriends mother was a twin.  Really increased her chances if having it.

Unlikely.  Usually skips a generation.  Your kids might have.

No, you are not. If you get one of those in vitros with multiple eggs, your chances will probably increase by a million % or more.
