A couple is expecting monozygotic twins. Which of the following correctly represents the number of ova and sperms that participated in the fertilization process to form these twins?

Step-by-step solution

Monozygotic twins are identical twins that develop from a single fertilized egg or zygote. The fertilization process involves the fusion of a single ovum and a single sperm. After fertilization, the resulting single zygote undergoes cleavage and splits into two separate embryos, which then develop into identical twins. Therefore, only one ovum and one sperm participate in the fertilization process to form monozygotic twins. Answer: One ovum and one sperm
