Premature birth and low birth weights, especially when under 3. Monozygotic twins who share a placenta can develop twin-to-twin transfusion syndrome.
This condition means that blood from one twin is being diverted into the other twin. One twin, the 'donor' twin, is small and anemic , the other, the 'recipient' twin, is large and polycythemic.
The lives of both twins are endangered by this condition. Stillbirths occurs when a fetus dies after 20 weeks of gestation.
There are two types of stillbirth, including intrauterine death and intrapartum death. Intrauterine death occurs when a baby dies during late pregnancy.
Intrapartum death, which is more common, occurs when a baby dies while the mother is giving birth. The cause of stillbirth is often unknown, but the rate of babies who are stillborn is higher in twins and multiple births.
Caesareans or inductions are advised after 38 weeks of pregnancy for twins, because the risk of stillbirth increases after this time.
Heterotopic pregnancy is an exceedingly rare type of dizygotic twinning in which one twin implants in the uterus as normal and the other remains in the fallopian tube as an ectopic pregnancy.
Ectopic pregnancies must be resolved because they can be life-threatening to the mother. However, in most cases, the intrauterine pregnancy can be salvaged.
For otherwise healthy twin pregnancies where both twins are head down a trial of vaginal delivery is recommended at between 37 and 38 weeks.
Twin studies are utilized in an attempt to determine how much of a particular trait is attributable to either genetics or environmental influence.
These studies compare monozygotic and dizygotic twins for medical , genetic , or psychological characteristics to try to isolate genetic influence from epigenetic and environmental influence.
Twins that have been separated early in life and raised in separate households are especially sought-after for these studies, which have been used widely in the exploration of human nature.
Classical twin studies are now being supplemented with molecular genetic studies which identify individual genes.
This phenomenon is known as heteropaternal superfecundation. One study estimates that the frequency of heteropaternal superfecundation among dizygotic twins, whose parents were involved in paternity suits, was approximately 2.
Dizygotic twins from biracial couples can sometimes be mixed twins , which exhibit differing ethnic and racial features.
One such pairing was born in London in to a white mother and Caribbean father. Among monozygotic twins, in extremely rare cases, twins have been born with different sexes one male, one female.
The probability of this is so small that multiples having different sexes is universally accepted as a sound basis for in utero clinical determination that the multiples are not monozygotic.
Another abnormality that can result in monozygotic twins of different sexes is if the egg is fertilized by a male sperm but during cell division only the X chromosome is duplicated.
This results in one normal male XY and one female with Turner syndrome 45,X. Monozygotic twins can develop differently, due to their genes being differently activated.
As of [update] , only two cases have been reported. Both ova are then fertilized, each by a different sperm, and the coalesced zygotes undergo further cell duplications developing as a chimeric blastomere.
If this blastomere then undergoes a twinning event, two embryos will be formed, with different paternal genetic information and identical maternal genetic information.
This results in a set of twins with identical gene sequence from the mother's side, but different sequences from the father's side.
Cells in each fetus carry chromosomes from either sperm, resulting in chimeras. This form had been speculated until only recently being recorded in Western medicine.
In , a study reported a case of a pair of living twins, which shared an identical set of maternal chromosomes, while each having a distinct set of paternal chromosomes, albeit from the same man, and thus they most likely share half of their father's genetic makeup.
The twins were both found to be chimeras. One was an intersex XX, and one a XY male. The exact mechanism of fertilization could not be determined but the study stated that it was unlikely to be a case of polar body twinning.
A second case of sesquizygotic twins was reported in Mirror image twins result when a fertilized egg splits later in the embryonic stage than normal timing, around day 9— This type of twinning could exhibit characteristics with reversed asymmetry, such as opposite dominant handedness, dental structure, or even organs situs inversus.
There is no DNA-based zygosity test that can determine if twins are indeed mirror image. There have been many studies highlighting the development of language in twins compared to single-born children.
These studies have converged on the notion that there is a greater rate of delay in language development in twins compared to their single-born counterparts.
Another term to describe what some people call "twin talk" is cryptophasia where a language is developed by twins that only they can understand.
The increased focused communication between two twins may isolate them from the social environment surrounding them. Idioglossia has been found to be a rare occurrence and the attention of scientists has shifted away from this idea.
However, there are researchers and scientists that say cryptophasia or idioglossia is not a rare phenomenon. Current research is looking into the impacts of a richer social environment for these twins to stimulate their development of language.
Twins are common in many mammal species, including cats , sheep , ferrets , giant pandas , dolphins , dogs , deer , marmosets , tamarins , and elephants.
A female calf that is the twin of a bull becomes partially masculinized and is known as a freemartin. From Wikipedia, the free encyclopedia.

The study stated that the occurrence of complications "was Mildessa Sauerkraut to be more likely with increasing twin-to-twin delivery time interval" and suggested that the interval be kept short, though it noted that the study did not examine causes of complications and did not control for factors such as the level of experience of the obstetrician, the wish of the women giving birth, or the "management strategies" of the procedure of delivering the second twin. If they occur early in fetal development, they will be present in a very large proportion of body cells.
