Can Twins Have Different Fathers?


Yes, it is possible for twins to have different fathers, a phenomenon known as heteropaternal superfecundation. This occurs when a woman releases multiple eggs during ovulation and has s£xual intercourse with different partners within a short timeframe. If each partner’s sp£rm fertilizes a separate egg, the result is fraternal twins with different biological fathers.

Unlike identical (monozygotic) twins, who originate from a single fertilized egg, fraternal (dizygotic) twins develop from two separate eggs fertilized by two different sperm. The timing of ovulation plays a crucial role in heteropaternal superfecundation, as the eggs must be released close enough together for both to be fertilized during the same menstrual cycle.

Genetic testing, specifically DNA analysis, is typically employed to confirm the presence of different biological fathers in such cases. This testing compares the genetic markers of the twins to determine their relatedness and can provide conclusive evidence of heteropaternal superfecundation
