Newser • • world
Key Points:
- British fraternal twins Michelle and Lavinia Osbourne discovered in 2022 through DNA tests that they have different fathers, a rare case of heteropaternal superfecundation where two eggs are fertilized by sperm from two men.
- The twins, born in Nottingham in 1976, were raised believing a man named James was their father, but DNA results revealed he was not biologically related to either sister.
- Michelle identified her biological father as Alex, who faced addiction and homelessness, while Lavinia's biological father was found to be Arthur, with whom she formed a close relationship.
- Despite the surprising genetic revelation, the sisters maintain a strong bond and emphasize that their relationship as twins remains unchanged, highlighting their enduring emotional connection.
- This case is one of fewer than two dozen documented worldwide and is reportedly the only known instance in the UK, though experts believe some cases may be undetected.
