How do twins run in the family?

Non-identical (fraternal) twins tend to run in families.

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.

Identical twins are the result of a single fertilised egg splitting, and this seems to be a random event..

How soon can twins be detected?

“You can guess as much as you want, but until you have the ultrasound examination, it’s all just speculation,” says Dr. Grunebaum. Luckily, most mamas don’t have to wait long to know for sure. “Today, twins can usually be diagnosed as early as six to seven weeks of the pregnancy,” he adds.

Can I have twins if my mother is a twin?

If the twins are present on your husband’s/partner’s side, it won’t influence your chances of having twins. Remember, the gene for hyperovulation is only a factor for the mother. If your mother (or your grandmother or aunt) was or had fraternal twins, you might have the gene.

Who is more likely to have twins?

A previous pregnancy — or, better yet, previous multiple pregnancies — may increase your chances of having twins. In fact, according to the , women between the ages of 35 to 40 with four or more children are three times more likely to have twins than a woman under 20 without children.

Which parent carries the gene for twins?

This is why fraternal twins run in families. However, only women ovulate. So, the mother’s genes control this and the fathers don’t. This is why having a background of twins in the family matters only if it is on the mother’s side.

What are the chances of having twins if there are twins in the family?

If a woman’s mother has fraternal twins, she is about 2 times more likely to have twins. This is why we often say the “risk” for having twins comes from the mother. It doesn’t matter if the dad also has fraternal twins in his family – his DNA won’t influence how many eggs the mom releases!

Do twins come from Mom or Dad?

According to Stanford, the likelihood of twins during any particular pregnancy comes from the mother, because, as they put it, “A father’s genes can’t make a woman release two eggs.” If you’re the woman who is trying to conceive though, it’s not just your mom’s genetics that matter.

How many generations do twins usually skip?

According to the Centers for Disease Control and Prevention (CDC), twin births have nearly doubled over the last 40 years.

Does the twin gene skip a generation?

However, any female children of twins could inherit a combination of genes that makes them more likely to release multiple eggs during ovulation (thanks to the DNA passed from their dad). This would make them more likely to have twins and give the appearance of the twins skipping a generation.
