Hereof, who carries the twin gene mother or father?
For a given pregnancy, the odds of conceiving fraternal twins are only determined by the mother's genetics, not the father's. Fraternal twins happen when two eggs are simultaneously fertilised instead of just one.
Similarly, how does twins run in the family? Non-identical (fraternal) twins tend to run in families. But identical twins don't. Non-identical twins are the result of two separate eggs being fertilised by two separate sperm. There is a gene that makes a woman more likely to release two or more eggs during ovulation, and it's this gene that runs in families.
Beside this, is the twin gene passed on by the male or female?
However, since only women ovulate, the connection is only valid on the mother's side of the family. While men can carry the gene and pass it on to their daughters, a family history of twins doesn't make them any more likely to have twins themselves.
Can twins be passed down on father's side?
Heredity on the father's side, however, does not increase a couple's odds of having multiples. This is true even if his family is packed with multiples. Men, of course, don't ovulate, so even if they've inherited that hyperovulation gene from their parents, it doesn't increase their own odds of conceiving twins.

A commonly held notion about twins is that they skip a generation.

There is no concrete scientific evidence that suggests twins skip a generation.Why are twins more common in older mothers?
Age. People over 30 are more likely to conceive twins.1 This is because the hormone FSH rises as a woman gets older.
