- A bi-paternal twins was found in Vietnam
- The twins share the same mother but has different fathers
- There are only 10 recorded cases of bi-paternal twins across the world
A rare of case of bi-paternal twins or twins fathered by two different fathers was reported in Vietnam.
Vietnam News said it was the first case of its kind ever recorded in Vietnam. There are only 10 recorded cases of bi-paternal twins across the world so far.
The twins, who are now two years old, look different. The babies were sent to Hanoi-based Centre for Genetic Analysis and Technology for DNA tests after one of them started growing thick and wavy hair, while the other has thin and straight hair.
The state-run Tuoi Tre newspaper said the husband requested genetic testing at the Hanoi lab to determine whether he was the biological father of both his wife’s twins.
The relatives of the Vietnamese husband pressured him to undergo DNA testing after noticing the stark differences in the children’s appearances.
The result of DNA test showed the man was related to only one of the babies.
To rule out the possibility that the wrong baby was given to them at the hospital, the mother also underwent DNA testing. The result showed she is the mother of both babies.
Le Dinh Luong, the president of Vietnam Genetics Association, said the case of two children with different fathers but have the same mother is rare; not only for Vietnam, but for the world.
“Our Centre for Genetic Analysis and Technology lab has tested and found a pair of bi-paternal twins. This is rare not only for Vietnam, but for the world,” he said.
Le Dinh Luong said there is a scientific explanation to the rare phenomenon.
“Women ovulate only one healthy egg per cycle but sometimes, there are two. If the woman had s*x with more than one man within two or three days then it’s possible that both eggs will be fertilized,” he said.
