After the DNA test, she found that only one of her kids showed positive for the DNA test while the other one did not. Though the phenomenon is extremely rare, it is not entirely impossible.
The girl remembered that she had had sex with another man and called him to take the test, which was positive. She didn’t know how this could happen as the babies are very similar.

The biological phenomenon of giving birth to twins with two different biological fathers is scientifically called heteroparental superfecundation.
One Set of Twins – Two Fathers: How Common is Superfecundation?
It is possible to happen when two eggs from the same mother are fertilized by different men. The babies share the mother’s genetic material, but they grow in different placentas.
This case occurs when a second ovary released during the same menstrual cycle is additionally fertilized by the sperm cells of a different man in separate intercourse.
The doctor emphasized the extreme rarity of the case. According to reports, there are only 20 other heteroparental superfecundations cases in the world.
The babies are now 16 months old and the young mum said one of the fathers help take care of them. It is understood that the name of only one of the men will be added to the birth certificate of the twins.
