Which parent carries the gene for twins?
The gene versions that increase the chance of hyperovulation can be passed down from parent to child. This is why fraternal twins run in families. However, only women ovulate. So, the mother’s genes control this and the fathers don’t.
What are the chances of a twin giving birth to twins?

One reason for this may be hyperovulation, which is a situation where the body releases two or more eggs during ovulation — basically a requirement for having fraternal twins.
Do twins skip a generation?
When both eggs are fertilized, the resulting siblings are fraternal twins. Because there is no known gene that influences this process, it is considered a mere coincidence when one extended family has multiple sets of identical twins. The notion that twins always skip a generation is also a myth.

It’s a common misconception that twins skip a generation in families. There is absolutely no evidence, other than circumstantial, that twins are more likely to occur every other generation.
Can you have twins if they don’t run in your family?
Since embryo splitting is a random spontaneous event that happens by chance, it doesn’t run in families. Genes are not involved and there’s no scientific evidence that being from a family with identical multiples has any impact on your odds of having twins. The same is not true for fraternal twins.
Could I be pregnant with twins again?
History of twins: Once you have a set of fraternal twins, you’re twice as likely to have another set in future pregnancies. Number of pregnancies: The more pregnancies you’ve had, the greater your chances of having twins.
How can I get twins?

According to the Centers for Disease Control and Prevention (CDC) , twin births have nearly doubled over the last 40 years.
How do I know if I’m pregnant with twins?
But the only way to confirm a twin pregnancy is with an ultrasound done at your doctor’s office, typically during the first trimester. Your doctor may also be able to confirm if you’re having fraternal or identical twins, but a DNA test can tell you for sure.
What are twins called that are born on different days?
It’s also possible to have twins that were conceived at different times in a process called superfetation. In exceedingly rare cases, a woman might release two eggs during ovulation, but not at the same time. In such cases, twins may actually be born on different days.
How early can twins be detected?
Are you wondering if you may be carrying more than just one baby? Many women say they could sense early on that they were carrying multiples. The only sure way to find out if you’re pregnant with twins is at your first ultrasound appointment at around 10 weeks.
Can folic acid cause twins?
Folic Acid Not Tied to Multiple Births. Jan. 31, 2003 — Women who take folic acid supplements before or during pregnancy are not any more likely to have a multiple birth, such as twins or triplets, according to new research.
What causes twin pregnancy?
Multiple pregnancy usually happens when more than one egg is fertilized. It also can happen when one egg is fertilized and then splits into 2 or more embryos that grow into 2 or more babies. When one fertilized egg splits into 2, the babies are called identical twins.
Can twins have different dads?
In rare cases, fraternal twins can be born from two different fathers in a phenomenon called heteropaternal superfecundation. Although uncommon, rare cases have been documented where a woman is pregnant by two different men at the same time.
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. FSH, or follicle-stimulating hormone, is responsible for the development of eggs in the ovaries before they are released.
Can you have twins naturally?
The American Society for Reproductive Medicine reports that twins happen naturally in about 1 out of every 250 pregnancies. The rate is much higher in women who get fertility treatments.
Are twins lucky?
In ancient times, the Yoruba viewed twins with suspicion, and sometimes sacrificed them. But now twins are considered lucky.
