Question

in oogenesis reduction division take place during​

Answer 1

Answer:

In oogenesis reduction division take place during the first meiotic division, in the formation of secondary oocytes (haploid) from primary oocytes (diploid).

Explanation:

Oogenesis is the process of the formation of the mature egg cell (female gamete). The process is initiated when oogonia (gamete mother cells) are formed within the fetal ovaries, in the embryonic development stage. These oogonia transform into primary oocytes by the continuous mitotic division, this process is called Oocytogenesis. The primary oocytes enter into prophase-$1$ of the meiosis-$1$, and are temporarily get halted the further division, and get surrounded by a layer of granulosa cells, called primary follicles. These follicles then transform into secondary follicles and later into tertiary follicles.

Once puberty reaches, the primary oocytes within the tertiary follicles, complete the meiosis-$1$ and forms secondary oocytes, which are half in chromosome number.

Answer 2

In oogenesis reduction division take place during​ the first meiotic division:

• Oogenesis is the formation of female gametes.
• The division takes place in the formation of secondary oocytes or haploids from primary oocytes or diploids.
• It is a process that forms when gamete mother cells are formed within the fetal ovaries.
• The primary oocytes enter into the Prophase-1 phase of the Meiosis-1 and get halted until puberty is reached.
• Once puberty is reached, the primary oocytes complete the Meiosis-1 and form secondary oocytes.
