A woman has given birth to twins who both have different dads, after she had sex with two men.
The mother, from Vietnam, and her husband got the surprising news when they took their two-year-old children for DNA tests because of their ‘strikingly different appearances’, The Mirror reports.
The couple were shocked to hear that only one of their twins was actually biologically related to the supposed father, according to local reports.
Unfortunately for the husband, tests ruled out the possibility of a hospital mix-up and both kids were related to the mother, meaning she must have slept with another man.
Le Dinh Luong, president of the Genetic Association of Vietnam, told AFP that the findings were extremely rare:
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.Advertisement
Bi-paternal twins are extremely rare but they can occur if two eggs from the same woman are fertilised by the sperm of two men during the same ovulation period.
The time window in which the eggs can be fertilised is very small, because although sperm cells are capable of living inside a woman’s body for four to five days, the lifespan of a woman’s egg is just 12 to 48 hours.
The exact circumstances surrounding the Vietnamese couple’s twins remains unclear. However, a local newspaper reports that the husband had been encouraged to take his children for DNA tests by his relatives, who noted that one of the twins did not look at all like him.
The pair were both born on the same day two years ago. But, despite being the same sex, one of them has thick, wavy hair while the other has thin and straight locks.
The unidentified family are now said to be looking for the best way to deal with the shocking test results. They could always give Jeremy Kyle a call?
