Question

Quizplus · Accepted Answer

Monozygotic (identical) twins develop when a single fertilized egg (zygote) splits into two, resulting in two genetically identical embryos. Therefore, they share 100% of their genes. Dizygotic (fraternal) twins, on the other hand, develop from two separate eggs fertilized by two different sperm and share about 50% of their genetic material, just like any other full siblings.
