Question

During the process of oogenesis in human female, the primary oocyte results in the formation of which of the following?
Choose the correct option.

• A. Unequal cells — a smaller haploid secondary oocyte and a larger diploid polar body
• B. Unequal cells — a larger haploid secondary oocyte and a smaller haploid polar body
• C. Unequal cells — a smaller diploid secondary oocyte and a larger haploid polar body
• D. Equal cells — a haploid secondary oocyte and a haploid polar body

Hint:

Oogenesis involves unequal cell divisions to conserve cytoplasm in the developing egg.

Answer 1

The Correct Option is B

During oogenesis, meiosis in the primary oocyte results in an unequal division of cytoplasm, producing a larger haploid secondary oocyte and a smaller haploid polar body. This ensures that the oocyte retains most of the cytoplasmic content for future embryonic development.
