Question

Quizplus · Accepted Answer

Monozygotic twins develop from a single fertilized egg that splits into two, resulting in two genetically identical individuals. As they share the same genetic material, they have a 100% genetic similarity. Dizygotic twins, on the other hand, develop from separate eggs fertilized by separate sperm, and therefore share an average of 50% of their genes, like any other siblings.
