Do twins come from the mother or father?
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..
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.
What are the odds of a twin having twins?
Here are the odds of having twins: 1 in 17 if the mother is a fraternal twin. 1 in 85 if the mother is an identical twin.
Can I have twins if I’m a twin?
Heredity: If you’re a twin, or if there are twins in your family, you’re slightly more likely to have a set yourself. Age: The older you are, the higher your chances of having fraternal twins or higher order multiples. Women age 35 or older produce more follicle-stimulating hormone (FSH) than younger women.
How do you know if you have twins?
It is impossible to definitively know whether you are carrying twins (or multiple babies) by simply gauging how you feel or going off of what a home pregnancy test shows. In fact, only an ultrasound can confirm a twin or multiple pregnancy.
How is the twin gene passed down?
When both eggs are fertilized, the resulting siblings are fraternal twins. Because this gene can be passed on, the tendency to have fraternal twins can in fact run in families. Identical twins, on the other hand, result from one fertilized egg randomly splitting in two, creating two siblings with identical DNA.
How do I up my chances of having twins?

How do you get twins?
Twins can occur either when two separate eggs become fertilized in the womb or when a single fertilized egg splits into two embryos. Having twins is more common now than it was in the past. According to the Centers for Disease Control and Prevention (CDC), twin births have nearly doubled over the last 40 years.
Can 2 sperm fertilize the same egg?
Occasionally, two sperm are known to fertilize a single egg; this ‘double fertilization’ is thought to happen in about 1% of human conceptions. An embryo created this way doesn’t usually survive, but a few cases are known to have made it — these children are chimaeras of cells with X and Y chromosomes.
Do twins skip a generation in family?
Yes, it can be hereditary to have fraternal twins, because “Fraternal twinning is caused by a gene on the X chromosome. … Fraternal twins can run in families where identical twins are likely a coincidence, and the idea that twins can skip a generation is simply just a myth.
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 it runs in my husband’s family?
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.
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.
Can twins have different dads?
It is possible for twins to have different fathers in a phenomenon called heteropaternal superfecundation, which occurs when two of a woman’s eggs are fertilized by sperm from two different men. Ordinarily, a woman becomes pregnant because one of her eggs has been fertilized by sperm.
