London: Is it possible that twins, born minutes apart, can have different fathers?
Few would have heard about such a possibility being a fact. But it is, indeed, true.
In a rare case, which has been and medically documented, twin sisters in the United Kingdom discovered almost five decades later that they don’t share the same father.
The 49-year-old twins Michelle and Lavinia Osbourne, born in Nottingham in 1976, recently learnt the truth after taking DNA tests at home.
According to the results of that test, though they have the same mother, they are biologically half-sisters.
In medical parlance, it’s a condition known as heteropaternal superfecundation.
Such a phenomenon occurs when a woman releases more than one egg during a cycle, which are fertilised by sperm from different men.
What is the probability of such a rare occurrence?
According to a BBC report, less two dozen such cases have been identified globally, and this is believed to be the first documented instance in the UK.
What were the twins’ emotions on discovering they are half-sisters?
Fo
r Lavinia, it was a mix of intuition and shock. “Maybe subconsciously I knew,” she told the BBC.
The test result, however, did affect her deeply.
“She was the one thing that belonged to me, and then she wasn’t,” Lavinia said, recalling their childhood.
Michelle, on the other hand, wasn’t surprised. “It’s super weird, super odd, super rare – but it makes sense,” she said.
The sisters grew up in difficult circumstances, as their mother struggled to provide stability. It all made them rely heavily on each other.
There was the uncertainty about their father since childhood as their mother had identified a man named James, who was largely absent.
Years later, Michelle questioned James as their father after seeing his photograph and noticing no resemblance. A DNA test confirmed he was not her biological father.
Further investigation led Michelle to a man named Alex. She recognised similarities in appearance, but said the meeting did not lead to a lasting bond.
Lavinia was initially reluctant, but eventually agreed to take a DNA test. Her results showed that Alex was not her father, confirming that she had a different biological dad. Michelle then traced him to a man named Arthur, and the sisters met him in London.
Lavinia formed a connection with Arthur and now meets him regularly. Arthur welcomed Michelle, too, telling her she could consider him a father figure.
In a strange twist, their mother died on the day Michelle received her DNA result.
