In what can be said as the rarest of the rare cases, a 19-year-old gave birth to twins who actually have two different biological fathers. This woman’s conception is one in a million. Reportedly, the anonymous 19-year-old, from Goias, Brazil, explained that she took a paternity test because she wanted to confirm who the father was.
There are only 20 similar occurrences in the world
As per the report, the mother had doubts about the father of her kids and confirmed that she did the DNA test using the sample of the person she had thought was the father. After the test, she found that only one of her kids showed positive for the DNA test while the other did not. “She then remembered that she had sex with a different man on the same day and when this second person took a test, it showed he was the second twin’s father,” says the report.
The woman’s physician Dr. Tulio Franco said it is feasible for this to occur when different males fertilize two eggs from the same mother. The doctor added that the kids have the same genetic structure as their mothers. He said that he never anticipated seeing a circumstance like this in his lifetime, in which there are only 20 other occurrences in the world.
This phenomenon was initially presented by Archer in 1810. “Although rare in humans, heteropaternal superfecundation is common in dogs, cats, and cows,” a report by The Guardian says.
