Nas profundezas de um simples teste de DNA doméstico, duas irmãs britânicas descobriram, em 2022, que a história de suas origens era mais complexa do que qualquer uma delas poderia imaginar. Michelle e Lavinia Osbourne, gêmeas nascidas em Nottingham em 1976, vieram ao mundo compartilhando o mesmo ventre, mas carregando o DNA de dois homens diferentes — um fenômeno chamado superfecundação heteropaternal, com apenas cerca de vinte casos documentados em todo o mundo.
