What is the rarest combination 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.

When identical twins are separated at birth, it allows researchers to compare the effect of genetics with the environment. This gives helps us answer the question: "is behaviour nature or nurture?"

Answer: Twins are two offspring produced by the same pregnancy.

Ask either twin "Which path would your twin tell me to take to get to the hospial?". Then go down the other path from the one they indicate. Reasoning: If the twin you ask is the truth-telling twin, he will know the other twin lies and will point you in the wrong direction, so will point the wrong way.

Septuplets (7)

The McCaughey septuplets (born 19 November 1997, in Des Moines, Iowa) are the world's first surviving set of septuplets.

In those cases, one twin will be born male (XY chromosomes) and the other will be born female (with a single X chromosome). So far there haven't been any documented examples of this happening in conjoined twins. Since they're a type of identical twins, it's theoretically possible. But it would be extremely rare!

However, few genes appear to be definitively linked to hyperovulation, so it could just be that genetics in general on the mother's side contribute to the probability of having fraternal twins. Heredity on the father's side, on the other hand, does not increase a couple's odds of having twins.

Definition. 00:00. Fraternal twins (also called dizygotic twins) result from the fertilization of two separate eggs with two different sperm during the same pregnancy. Fraternal twins may not have the same sex or appearance.

Your first year of raising twins will be tough. Expect less sleep, as your world will revolve around feeding your twins, burping them, changing them and putting them to sleep, all while constantly washing two sets of everything from clothes to feeding bottles. Financial costs are also higher with twins.

Heredity – a woman is more likely to conceive fraternal twins if she is a fraternal twin, has already had fraternal twins, or has siblings who are fraternal twins. These women are hyper-ovulators and are able to produce more than one egg at a time.

Which twin is older? ›

Who is the elder in twins? This should be pretty obvious, it's the twin born first. Although unless something goes very wrong with the delivery, the time is so close that there really isn't a elder or younger in twins.

“Identical twins can be different sexes due to a phenomenon called gonadal dysgenesis, where mutations or changes occur in the genes that determine the development of genitalia,” says Dr. Andrews.

Names for these include the following: twins – two fetuses. triplets – three fetuses. quadruplets – four fetuses.

You've probably heard of identical and fraternal twins, but a report released this week says there's a third kind -- sesquizygous twins or "semi-identical." Researchers say they share anywhere from 50 to 100% of their genomes.

Give the answer to this riddle: Two girls were born to the same mother, on the same day, at the same time, in the same month and year and yet they're not twins. How can this be ? Those who answered that the two babies are two sets of triplets are correct!

Dizygotic twins are the most common type and are known as fraternal twins. Two-thirds of all sets of twins are dizygotic. When two eggs are fertilized during the same pregnancy, the result is a set of dizygotic twins. They are fertilized by two different sperm.

While there are risks associated with all twin pregnancies, dizygotic (fraternal) twin pregnancies usually bring about the least amount of complications, carrying the lowest risk of all types of twins. Worse complications are possible with monozygotic (identical) twins because the embryo is dividing.

Mixed-gender twins are the most common type of fraternals, some 50 percent are boy-girl. To understand this combination: Males have XY chromosomes, females have XX chromosomes. You have a girl twin when the father's X chromosome combines with the mother's X chromosome.

Male–male twins: Sometimes called fraternal (unrelated to zygosity) twins (25%). Female-male twins: This is the most common pairing (50%), encompassing both "female-male" (25%) and "male-female" (25%) twins.
