During oogenesis, an oogonium gives rise to primary oocytes. These primary oocytes then undergo meiosis to become secondary oocytes.
Oogenesis in rats involves the development of ova (egg cells) in the ovaries through a series of cell divisions. It starts with the production of primary oocytes during fetal development, which then undergo meiosis to become secondary oocytes. These secondary oocytes are released during ovulation, and if fertilized by sperm, can develop into embryos.
Ova are formed through a process called oogenesis, which begins with the development of oogonia (early ova) in the ovaries. Oogonia undergo mitotic division to produce primary oocytes, which then undergo meiosis to form secondary oocytes. These secondary oocytes are released during ovulation and, if fertilized, develop into mature ova.
From 100 primary oocytes, typically only 100 ova would be produced, as each primary oocyte undergoes meiosis to ultimately yield one ovum. However, during this process, each primary oocyte also produces three polar bodies, which are non-functional and do not develop into ova. Thus, while 100 primary oocytes lead to the production of 100 ova, the total output also includes 300 polar bodies, resulting in a total of 400 cells produced from the initial 100 primary oocytes.
During oogenesis, one primary sex cell produces one mature egg (ovum) along with three polar bodies, resulting in a total of four gametes. In contrast, during spermatogenesis, one primary sex cell produces four mature sperm cells (spermatozoa), resulting in a total of four gametes.

Eggs develop in the ovaries through a process called oogenesis. It begins with the division of stem cells in the ovary, which develop into primary oocytes. These primary oocytes then undergo meiosis to produce secondary oocytes, which are eventually released during ovulation.

Oogenesis is the process by which female germ cells, called oocytes, develop into mature eggs. It involves the growth and maturation of oocytes in the ovaries through various stages, ultimately leading to the release of a mature egg during ovulation.

A primary oocyte
Primary oocytes are diploid cells that have undergone DNA replication but are arrested in prophase I of meiosis, whereas secondary oocytes are haploid cells resulting from the division of primary oocyte after completing meiosis I. Secondary oocytes are arrested in metaphase II and are released during ovulation, while primary oocytes are present in the ovaries prior to puberty.
During oogenesis, one primary sex cell produces one mature egg (ovum) along with three polar bodies, resulting in a total of four gametes. In contrast, during spermatogenesis, one primary sex cell produces four mature sperm cells (spermatozoa), resulting in a total of four gametes.
Oogenesis is the process of female gamete (egg) formation that occurs in the ovaries. It involves the maturation of oocytes (immature eggs) through several stages, culminating in the release of a mature egg during ovulation. Unlike spermatogenesis in males, where sperm are continuously produced throughout life, oogenesis is a finite process that begins before birth and is typically completed after menopause.
42 daughter cells are produced and about 900 ugly cells
They are produced in the ovaries. However, fertilization takes place in the Fallopian Tubes.
The meiosis of egg formation is called oogenesis. During oogenesis, a primary oocyte undergoes two divisions to produce a single mature egg cell.
