Trizygotic or fraternal triplets are formed when three separate eggs are fertilised by three separate sperm. The babies can be the same or opposite genders. This means that it's possible to have anyone of the following combinations of babies – three girls/three boys or, one girl and two boys or two girls and one boy.
Trizygotic or fraternal triplets can be the same or opposite genders (three boys / three girls / one boy, two girls / two boys, one girl). Triplets can also happen when two separate eggs are fertilized by two different sperm, and one of those eggs splits into two, forming monozygotic (identical) twins.
The majority of triplets are what is known as trizygotic. This is because they are formed when three separate, individual eggs are fertilised by three separate sperm. These babies share the same characteristics as any other siblings with the same biological parents. They can be the same or opposite genders.
And the chances that they will be two of one sex and one of the other are 75 percent. (Two boys and one girl = 37.5 percent; two girls and one boy = 37.5 percent.)
Monochorionic-triplet pregnancies are exceedingly rare with a reported incidence of 1 in 100,000 births. 2 3. Monozygotic multiple gestations occur when a zygote splits into two or more genetically identical embryos.
Triplets don't always have to have three notes in them: the notes of the triplet just need to add up to three of whatever value there would normally be two of.
It is possible to have triplets where two of the babies are identical twins (and may share one placenta, and even one sac) and the third baby is non-identical (with completely separate placenta and sac).
Naturally conceived triplets occur in about one and every 10,000 pregnancies.
Can triplets have three different fathers? Yes, it is possible. Because superfecundation happens from different sexual encounters, it's possible that a woman is pregnant with triplets or twins with different fathers. The number of babies depends on the number of ova released by the woman in that one cycle.
Giving birth to triplets or more vaginally is very rare. It is not recommended because of the higher risk of labour complications and infant mortality. Since almost all triplets or more will be born prematurely, they will need special care. This may include a stay in a neonatal intensive care unit (NICU).
Of triplet pregnancies, 98% of all babies born after 28 weeks gestation survive! Of course sadly, this is not the case for every pregnancy, triplet or otherwise, and unexplained losses can occur at any time in the pregnancy.
It's not that unusual to have 3 children of the same gender in a row. This actually happens in one out of four couples who have 3 children.
“Most experts put the odds of identical triplets at one in 200 million births,” Tiberius said. “I talked to a statistician and apparently the odds of a 45 year old having identical triplets are one in 20 billion.” It's quite rare to become pregnant without medical intervention at 45, according to Dr.
Naturally, twins occur in about one in 250 pregnancies, triplets in about one in 10,000 pregnancies, and quadruplets in about one in 700,000 pregnancies. The main factor that increases your chances of having a multiple pregnancy is the use of infertility treatment, but there are other factors.
The Dionne quintuplets (born 28 May 1934, near Corbeil, Ontario, Canada) were the first quintuplets known to survive infancy. The five girls (Yvonne, Annette, Cecile, Emilie and Marie) were also the only set of identical quintuplets known to live into adulthood.
The Kirchner triplets, Catherine, Marguerite, and Frances (born 23 August 1920 in Brooklyn, NY), believed to be the oldest identical living triplets in the United States.
In music theory, a triplet is a three-note pattern that fills the duration of a typical two-note pattern. Each note in a triplet has equal rhythmic value.
Triplets, quadruplets, quintuplets, sextuplets or more can be a combination both of identical and fraternal multiples.
Monoamniotic-monochorionic Twins
This is the rarest type of twin, and it means a riskier pregnancy as the babies can get tangled in their own umbilical cords. If you have monoamniotic-monochorionic twins, your healthcare provider will monitor your pregnancy closely.
Are Di-Di Twins Usually the Same Gender? While identical twins will always be the same gender, di-di fraternal twins can go either way. You can end up with girl-girl twins, boy-boy twins, or boy-girl twins. In fact, science has found that the most common type of fraternal twins is boy-girl!
Around the world, the chances of having twins for a couple is 1 per cent, and the rate for China is 0.5 per cent, according to Yu Rong, an obstetrician from Xuanwu Hospital in Beijing.
