Tweeling girls have  two dads

A Vietnamese father of twins got the shock of his life when he learnt that one of the laaities is not his.

DNA testing this week revealed an extremely rare case of bi-paternal twins – twins with different fathers but the same mother.

The twins, born to a Vietnamese couple, were recently taken for testing after the father noticed stark differences in the children’s appearances, according to local reports.

“Our Centre for Genetic Analysis and Technology lab has tested and found a pair of bi-paternal twins,” Le Dinh Luong, president of the Genetic Association of Vietnam, told AFP.

“This is rare not only for Vietnam, but for the world.”

This can happen if two eggs from the same mother are fertilised by sperm from two different men during separate acts of sexual intercourse.

The twins are now two years old. One of them has thick, wavy hair, while the other has thin, straight hair.

Ruling out a hospital mix-up, his wife was found to be the biological mother of both children.

In the United States last year, a court ruled that 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.
