It was when she noticed that despite their similar appearance, her twins had some differences such as size, that the new mother had one of the two dads perform a DNA test when her children were eight months old. At the time of the results, the girl discovered that the man was the father of one of the two twins.

For the website Brazilian , the mother of infants testified anonymously: I was amazed at the results. I didn't know this could happen. They look a lot alike. [...] I remembered that I had sex with another man and I called him to take the test, which was positive “, completes the mother.
