The correct answer is c. are as genetically similar as other siblings.

Explanation:

Dizygotic twin are the twins which developes from two different fertilized egg. So a dizygotic twins can be both male, both female or one male and one female. As dizygotic twins are produced by fertilization of two different gametes, therefore, they share just half of their gene like other siblings share.

Therefore dizygotic twins are as genetically similar as other siblings. Monozygotic twins are the twins that are produced from a single fertilized egg which splits into two eggs. So monozygotic twins share 100% gene, therefore, they are called identical twins. So the correct answer is c.
