When relatives insisted his twins did not look alike, the 34-year-old man from northern Hňa Běnh province in Vietnam took the infants for DNA tests. According to the online newspaper Dan Tri, one twin had thick wavy hair, while the other had thin and straight hair.
What the tests revealed marked a rare victory against the odds in reproductive biology – though that was perhaps not the first thought to cross the parents’ minds. The newborn twins, according to the Centre for Genetic Analysis and Technology lab in Hanoi, had two different fathers.
The man from Hňa Běnh was the father of only one of the twins. The Y chromosome from the other infant did not match his own.
Le Dinh Luong, the president of the Genetic Association of Vietnam, said his lab had tested and found a pair of bi-paternal twins, adding: “This is rare not only for Vietnam, but for the world.” The twins, who are now two, were born on the same day and are the same sex.
DNA testing of the mother to rule out a mix-up at the hospital dismissed that possibility, and confirmed that both children were hers, the newspaper said.
The likelihood of him not being present when that other spermatozoďde got to that ovule is pretty low. That's why I personally didn't think of "infidelity". But if she was indeed unfaithful, good day for science and bad day for the man.
