Question

Quizplus · Accepted Answer

Dizygotic twins, also called fraternal twins, develop from two separate eggs fertilized by two different sperm. Therefore, they share on average 50% of their genetic material, just like any other siblings born at different times. Monozygotic twins, on the other hand, develop from a single fertilized egg that splits into two embryos, resulting in two individuals who are genetically identical to each other.
