Question

Why is a single ovum produced by oogenesis?

Answer 1

Single ovum is produced in oogenesis because:

1. Female gametogenesis, also known as oogenesis, results in mature eggs.
2. As a result of meiosis, only one egg is generated from four haploid cells.
3. The primary oocyte undergoes the first meiotic division, resulting in the formation of a secondary oocyte (haploid).
4. A second meiosis division occurs in secondary oocytes, resulting in a haploid ovum.
5. As a result of meiosis, one egg is produced, which contains the most important nutrients, cytoplasm, and organelles.
6. Oogenesis is the process of producing haploid ova (egg) from diploid egg mother cells in the ovary (female gonad).
