Two polish twins born to a single mother apparently have different fathers.

This is only the seventh such know case in the world. A polish mother has given birth to twins who have different fathers. The doctor who conducted the DNA Tests said that this was a very very rare paternity. This woman was having relations with her husband and also an affair with someone else, reported broadcaster TVN24.

The woman, whose name was not given had filed a divorce with her husband after finding out the truth. She later conducted tests to prove it wrong but ended up getting completely opposite results. For those interested in the details, such rare cases are possible when a woman produces two eggs and has sex with another partner while she is ovulating, local media reported.
