Which of the following processes occurs both in oogenesis and in the development of sperm?
Formation of polar bodies
Meiosis
Development of a Graafian follicle
Fertilization
The Correct Answer is B
a. Formation of polar bodies: Formation of polar bodies occurs only in oogenesis, not in spermatogenesis.
b. Meiosis: Correct. Both oogenesis and spermatogenesis involve meiosis, the process of cell division that reduces the chromosome number by half.
c. Development of a Graafian follicle: This is specific to oogenesis. The Graafian follicle is the mature ovarian follicle.
d. Fertilization: Fertilization is the union of sperm and egg, not a process that occurs during the development of either gamete.
