What happened: Lavinia and Michelle are twins born minutes apart but have different fathers, a unique case recorded in the UK.
Why it matters:
- This case highlights the rare biological phenomenon of heteropaternal superfecundation.
- It has implications for family law, paternity testing, and genetic understanding.
MNN Take: Twins with different fathers occur when a woman releases multiple eggs in one cycle and has sexual relations with more than one man, leading to fertilisation by different sperm.
