A man has generated outrage online after describing how a school DNA test purportedly revealed a disturbing secret about his family.

According to him, the event began when his oldest daughter was requested to undergo a DNA test for a school heritage project.

“My oldest daughter came to me very sad because apparently me and her were not related. When she told me this, I had to keep a straight face because the immediate shock was just, wow.”

The dad escorted his daughter to a paternity test, which revealed that he was not her real father.

He claimed that he then decided to test his other children in the hopes of finding an error.

“I went to my next oldest child. Not mine. I went to the one below that. Not mine. I immediately was like, let me go talk to my wife about this.”

According to him, his wife initially refuted the allegations and questioned why he would trust the test results over her statements.

However, he said that she eventually acknowledged to being unfaithful, and that further investigations revealed that each of the children had separate biological dads.

The report has sparked widespread outrage online, with many social media users expressing astonishment and others debating the significance of DNA testing and trust in partnerships.
