Set Of Twins Can Have Different Fathers- Study Shows

It is possible for twins to have different fathers,  We all know that siblings can have different fathers – technically making them half-siblings. Same thing is also applicable to twins. It is possible to have a set of twin from a different father.
In fact, a study estimates that as many as 1 in 400 sets of fraternal twins is “bipaternal.” this is possible when two eggs from the same mother get fertilized by two different fathers – within the same ovulation period.
Let take some animals as an example. According to Joann Boughman,  the executive vice president of the American Society  Of Human Genetics, “Female dogs ovulate multiple eggs,” ” and when a dog is in heat, any male dog in the vicinity will attempt to mount her, so each egg could be fertilized by a different father, producing a litter of puppies that don’t resemble each other in the slightest.”
Humans are not dogs, of course, and most of the time, women ovulate only one healthy egg per cycle. Fraternal twins occur when women ovulate two healthy eggs and both get fertilized.
“superfecundation” happens when two eggs are ovulated during the same cycle and fertilized at different points within the six-day fertility window,(ovulation period)  resulting in a bouncing pair of twins.
When we see twins, we may assume that both eggs were fertilized during a single act of intercourse. But it’s quite possible for one egg to be fertilized during one act of intercourse, and the other during another. For example, consider a couple that has sex in the morning, followed by another round of sex in the evening.
“Heteropaternal  Superfacuundation” this is when a woman has sex with more than one man while she is fertile. This means each egg can be fertilized by different fathers.
Recall that  Vanguard Newspaper reported a  case of Marcus and Lucas on January 14, 2017, Marcus and Lucas are twins with two different fathers. They are one of only three known sets of twins in the world who are genetic half-brothers.
Their mother Charlotte became pregnant when she slept with ex-husband Michael and new boyfriend Tommy within 48 hoursNine months latershe gave birth to twins Marcus and Lucas, who are genetic half-brothers because they were fathered by both men.
Marcus was fathered by Michael and Lucas by Tommy. Charlotte, who already had two sons by Michael Nielsen, divorced him in August 2004. She began dating Tommy even as Michael still hoped to get back together with her and in the heat of the moment they ended up in bed together.
Charlotte kept quiet about the incident with Michael which was a one-off and went to bed with Tommy. She later discovered she was pregnant with twins and decided to inform both men either could be the father of the twins.
Marcus and Lucas were just a couple of weeks old when it was discovered they didn’t look alike. Tommy and Michael took a DNA test to find out for certain that the boys had different fathers. The test proved the twins did indeed have different fathers. It stated: “The results do not imply that the children Lucas Hilbrandt Nielsen and Marcus Hilbrandt Nielsen have the same biological father. The probability of this preclusion exceeds 99.99 per cent.”
Similar cases of bi-paternal twins have popped up over time. In May 2015, a case in New Jersey made news when a court ruled that a father did not have to pay child support for a second twin because DNA evidence showed that he was a father to only one.
The mother gave birth to twin girls and named a romantic partner, as the father of both children when applying for public assistance. But after she admitted that she had sex with another unidentified man within a week of having had sex with the bonafide partner, a DNA test was ordered. The test results confirmed both men fathered each of the girls.
CNN also reported fraternal twins in Vietnam found to have different fathers in an “extremely rare” case that came to light through a DNA test.
They had their DNA tested at the Centre for Genetic Analysis and Technology in Hanoi because family members had been vocal about notable differences in the children’s appearance.
There are rare cases in which a woman may ovulate more than once during her cycle, meaning that two eggs would be released at different times. There are less than 10 known cases of twins with different fathers in the world. Fraternal twins make up about 2 percent of pregnancies and bi-paternal twins are a fraction of them.
But twins, who don’t look alike, do not necessarily have separate fathers. Twins who have the same father can look completely different and may even appear to be of different races. Less than one (0.001) per cent of fraternal twins are from different fathers.
According to Dr. Virginia Beckett of the Royal College of Obstetricians and Gynaecologists, if a woman is going to sleep with more than one partner at the same time it is perfectly feasible that if she has twins they could have different fathers.
“In this case, these twins were conceived at the same time even though the mother did not have sex with the fathers at the same time. The sperm from the first man would have been in her fallopian tube, where it is effective for three to four days. Then she had sex with the second man and released two eggs. The eggs, which live for 24 hours, were fertilised by different sperm from the different men. The science is easily explained, but it may have been less easy for the mother to explain.
