thebalanced.newsUK Twin Sisters Discover Different Fathers in Rare Biological Case
Twin sisters Michelle and Lavinia Osbourne from Nottingham, UK, discovered in their late 40s that they have different biological fathers, a rare case of heteropaternal superfecundation. Born minutes apart in 1976 and raised believing they shared the same father, DNA tests revealed they are half-sisters conceived from two eggs fertilised by sperm from different men. The sisters grew up in challenging circumstances and only learned the truth decades later, making this the first documented UK case of this phenomenon.
