Twins with DIFFERENT fathers??? Don't miss this shocking DNA test that reveals the children had the same mother but different fathers.

Scientists say if a woman has more than one sexual partner while she is ovulating, there is a miniscule chance different sperm cells can fertilise two separate eggs.

A Vietnamese woman has given birth to twins with different fathers. Doctors treating her say the remarkable case - defined medically as a set of bi-paternal twins - is extremely rare.

The twins, who are now two years old, were born the same day and are the same sex.

However their 34-year-old father underwent DNA testing after being pressured by his family because the children did not look alike.

One has thick wavy hair while the other has thin and straight hair, the online newspaper Dan Tri reports. 

To rule out a hospital mix-up, DNA testing of the mother revealed she was the mother of both children, the report said.

Professor Le Dinh Luong, president of the Genetic Association of Vietnam, said DNA testing at his Hanoi lab confirmed the twins have different fathers.

He explained bi-paternal twins could occur if two eggs from the same mother were fertilized by sperm from two different men within a seven-day ovulation period.

Basically, if a woman has more than one sexual partner while she is ovulating, there is a miniscule chance that different sperm cells can fertilise two separate eggs.

Professor Luong added this was the first such case he was aware of in Vietnam, and only seven cases had been reported in medical literature until recently.

However he declined to give details of his client, who is from the northern Hoa Binh province, due to confidentiality.

Another case of bi-paternal twins was reported in the US last year, when a court ruled a man was only required to pay child support for one girl in a set of twins after DNA tests proved he was not the father of both.

And in 2009, a mother’s fling resulted in her bearing twins by different fathers.

Justin and Jordan Washington arrived in the world within just seven minutes of each other.

But each has a different father because their mother Mia Washington conceived two babies by different men at the same time.

Fortunately, her partner James agreed to forgive her infidelity - and to raise both twins as his own.

Ms Washington, from Dallas, Texas, said at the time: 'Out of all the people in America and all the people in the world, this had to happen to me.'

The truth emerged when she noticed the twins had different facial features.

A paternity test confirmed her fears - and showed there was only a 0.001 chance that Justin and Jordan have the same father.

Commenting on this case, Genny Thibodeaux, from Clear Diagnostics DNA Lab, said: It's very crazy, most people don't believe it can happen but it really can.'
