After DNA testing, she found that only one of her children showed positive for the DNA test while the other did not. Although the occurrence is extremely rare, it is not entirely impossible.
The girl remembered that she had had sex with another man and called him to get tested, which was positive. She didn’t know how this could happen because the children are so similar.

The biological phenomenon of fathering twins with two different biological fathers is scientifically called heteroparental superfecundation.
A set of twins – two fathers: how common is superfecundation?
This is possible when two eggs from the same mother are fertilized by different males. Babies share the mother’s genetic material, but they grow in separate placentas.
This is the case when a second ovum released during the same menstrual cycle is additionally fertilized by sperm cells from a different man in a different sexual intercourse.
The doctor emphasized the extreme rarity of the case. According to reports, there are only 20 other heterosexual superfecundation cases in the world.
The children are now 16 months old and the young mother said that one of the fathers helps take care of them. It is understood that only one male’s name will be added to the twins’ birth certificates.
