Because fraternal, or dizygotic, twins are 2 separate fertilized eggs, they usually develop 2 separate amniotic sacs, placentas, and supporting structures.
Identical, or monozygotic, twins may or may not share the same amniotic sac, depending on how early the single fertilized egg divides into 2
.
Can a twin carry twins?
Generation 2:
The female twin has a set of twins
. One of them inherits the gene for hyperovulation. The male twin does not have twins, but he passes the gene for hyperovulation to his daughter. Generation 3: The daughters who inherited the gene for hyperovulation give birth to twins.
Do twins carry through 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.
Is it true that twins skip a generation?
This belief is based on the assumption that twinning is genetic and runs in families. However, if that was truly the case—if there was a twin gene—then twins would occur with predictable frequency in those families that carry the gene.
There is no concrete scientific evidence that suggests twins skip a generation
.
Can I have twins if my husband 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.
Can a baby eat its twin in the womb?
Vanishing twin syndrome was first recognized in 1945. This occurs when a twin or multiple disappears in the uterus during pregnancy as a result of a miscarriage of one twin or multiple.
The fetal tissue is absorbed by the other twin, multiple, placenta or the mother
.
What is a mono twin?
“Mono Mono twins are
identical twins that share the same amniotic sac and placenta in utero
,” says Elaine Moore, Charge Nurse at McMaster Children's Hospital (MCH). They develop when an embryo doesn't split until after the amniotic sac is formed.

Can you have twins even if they don't run in the family?
Everyone has the same chance of having identical twins: about 1 in 250.
Identical twins do not run in families
. But there are some factors that make having non-identical twins more likely: non-identical twins are more common in some ethnic groups, with the highest rate among Nigerians and the lowest among Japanese.
Can twins happen with no family history?
Identical twinning and family heredity
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.
How likely am I to have twins if my dad is a twin?
According to The American Society for Reproductive Medicine, women who are fraternal twins have a 1 in 60 chance of having twins, and men who are fraternal twins have a
1 in 125
chance of fathering twins.
Can twins have different fathers?
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.
Can twins come from the father's side?
However, for a given pregnancy, only the mother's genetics matter. Fraternal twins happen when two eggs are simultaneously fertilized instead of just one.
A father's genes can't make a woman release two eggs.
Is there a higher chance of having twins if you are a twin?
Your chances of having fraternal twins may be higher if you're a fraternal twin yourself or if fraternal twins run in your family
. 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.
Can a male twin have twins?
A man with a family history of twins may carry the gene, but it won't mean he can father a set of non-identical twins
. The gene is only expressed through women who ovulate. If he has daughters, they may inherit the gene, and one day go on to have fraternal twins.
Do twins have the same blood type?
Monozygotic (identical) twins will have the same blood type, with a few very rare exceptions
. Dizygotic (fraternal) twins may have the same blood type, or they may have different types. Therefore, it may be concluded that twins with differing blood types are dizygotic, or fraternal.
How often do twins have twins?

What happens if 1 twin dies in the womb?
The death of one fetus in a twin pregnancy can be an unexpected and sad event. But
often the health of the remaining fetus is unaffected and the pregnancy will continue to a healthy birth
. This is particularly true when the death of a co-twin is early in the pregnancy.
Do twins fight in the womb?
Twins have been filmed ‘punching and kicking each other' while still in their mother's womb
. The foetuses, who share an amniotic sac, appear to be having a bout of boxing as one reaches out to shove the other one, then vice versa.
Can twins feel when the other dies?
When a twin dies, the twinless twin longs to reconnect.
The twinless twin may have phantom pain or feel half dead
. He or she may feel a need to represent both him or herself and the deceased twin or may even take on behaviors of the deceased twin.
What are Momo twins?
Understanding Monoaminotic ‘Momo' Twins
Monochorionic twins are
identical twins who share a single placenta
. They represent around 70% of identical twin pregnancies. Monochorionic-diamniotic twins are identical twins who share a placenta, but each has their own amniotic sac.
What are Didi twins?
In a di/di pregnancy (more scientifically referred to as a dichorionic diamniotic pregnancy)
the twins each have their own chorionic and amniotic sacs
. Essentially, each of the babies is growing like they would as a singleton, but just a little more cramped, because they're sharing the same womb.
What is the rarest type of twins?
Monoamniotic-monochorionic Twins
These types of twins share a chorion, placenta, and an amniotic sac. This is the rarest type of twin, and it means a riskier pregnancy as the babies can get tangled in their own umbilical cords.
