A Chinese woman just had twins with 2 different fathers — here’s how that’s possible
But, for a woman in New Jersey suing for child support, things are a little more complicated. It turns out the man she thought was the father of her twins was only the father of one of the pair.
Here are the different types of multiple births:. In this case, two different sperm impregnate two different eggs. This is what happened to the woman in New Jersey. One child was the product of her relationship with the man she brought to court, and the other child was conceived during a separate encounter with another man. While this phenomenon is rare, research suggests it does happen from time to time.
They occur when an egg divides in two during ovulation, creating a primary body and a polar body, both of which have the same genetics. In most cases, the polar body, which has less cytoplasm, will die off, but in some cases both the primary body and the polar body will be fertilized by separate sperm creating twins with identical genetics from the mother and different genetics from the father.
The two bodies, soon to be babies, share the same genetics and look the same. Things can get complicated when you start dealing with triplets, quintuplets, and even bigger single-pregnancy broods. For instance, a mother having triplets could have identical twins from the same egg and a third child from an entirely different egg and sperm. Once you start to mix and match like that, the possible combinations—to say nothing of the dynamics of the playroom—can get very complex.

C onstance Wu, of Crazy Rich Asians , is in talks to star in a new romcom. Apparently, her character is a bit ditzy — a classic romcom trope. But this ditziness will lead to what I am fairly sure will become a new romcom trope: heteropaternal superfecundation. He explains that heteropaternal superfecundation occurs when a woman gives birth to twins with different biological fathers. Once you can get past all the polysyllables, the romcom possibilities are endless: mistaken identity, twins who look comically different see Arnold Schwarzenegger and Danny DeVito in Twins , competing suitors. Although rare in humans, heteropaternal superfecundation is common in dogs, cats and cows, Carroll explains. That is one way to look at it. So how does superfecundation with multiple fathers happen at all?
Paternity pay and leave
We all know that siblings can have different fathers — technically making them half-siblings — but what about twins? Yes, it can happen. In fact, one study estimates that as many as 1 in sets of fraternal twins is "bipaternal. How is it possible?

The Science of How Women Can Have Twins With 2 Different Fathers
Soon after the birth of her twin babies, a Chinese woman and her husband noticed something strange — the two babies looked pretty different, and only one resembled the husband. Following a DNA test, the couple learned that the babies were actually from two different fathers and the mother then revealed she had a previous one-night stand, Vice reported. Although cases like this are rare, they do happen.
Can you get pregnant if you are already pregnant and would the result be twins? Superfetation is the formation of a fetus while another fetus is already present in the uterus. Essentially, it describes a situation where a woman becomes pregnant when she is already pregnant. It is believed that this is a very rare event and only a few cases have been reported and verified. Superfetation occurs when ova from two separate menstrual cycles are released, fertilized, and then implant in the uterus. Normally, once a woman is impregnated, physical and hormonal effects would make this impossible.
Superfetation: Twins Conceived at Different Times
Back to Pregnancy. It depends on the type of twins. There's no evidence that identical twins run in families. However, non-identical twins can run in families. A couple is more likely to have twins if there are twins in the woman's family. Identical twins happen when 1 fertilised embryo splits into 2.
Error: This is required. Error: Not a valid value. In every couples trying for a baby, the woman will get pregnant within one year in 80 to 90 cases. The rest will find it takes longer, or they may need help to conceive.
A California woman became pregnant while she was already pregnant, in an extremely rare case that resulted in her carrying "twins" with two different sets of parents. The year-old woman, Jessica Allen, agreed to be a gestational surrogate for a Chinese couple that she met through a surrogacy agency in southern California, according to the New York Post. In April , doctors used in vitro fertilization to produce an embryo for the Chinese couple, and implanted that embryo in Allen's uterus.
Superfecundation is the fertilization of two or more ova from the same cycle by sperm from separate acts of sexual intercourse , which can lead to twin babies from two separate biological fathers. Homopaternal superfecundation refers to the fertilization of two separate ova from the same father, leading to fraternal twins ;  while heteropaternal superfecundation is referred to as a form of atypical twinning where, genetically, the twins are half siblings. Superfecundation, while rare, can occur through either a complex single occurrence of sexual intercourse, separate occurrences of sexual intercourse, or through artificial insemination. Superfecundation most commonly happens within hours or days of the first instance of fertilization with ova released during the same cycle.
