In which of the following options is mitotic division involved?
Correct answer: A. Oogonium to primary oocyte
- A. Oogonium to primary oocyte
- B. Primary oocyte to secondary oocyte
- C. Secondary oocyte to egg
- D. None of the given options
Explanation
In oogenesis, diploid oogonium goes through mitosis until one develops into a primary oocyte, which will begin the first meiotic division, but then arrest; it will finish this division as it develops in the follicle, giving rise to a haploid secondary oocyte and a smaller polar body. Thus, "Option A" is the correct answer.
