Answer:
Fraternal twins are dizygotic and Identical twins are monozygotic.
Step-by-step explanation:
Fraternal twins are dizygotic, meaning that they developed from two different eggs fertilized by two different sperms. Their genetic code is as similar (or dissimilar) as any other siblings. Identical twins are monozygotic, meaning that they developed from the same fertilized egg, and so have nearly identical genetic code.
