Final answer:
Oogenesis in humans typically results in the formation of one mature egg from a single initial oocyte after meiosis.
Step-by-step explanation:
From a single initial oocyte, only one mature egg is produced through the process of oogenesis. During the reproductive period, starting from puberty, a woman’s ovaries release approximately one egg per month signaling her reproductive maturity. The surge of luteinizing hormone before ovulation triggers the resumption of meiosis in a primary oocyte, which leads to the formation of unequal cells: a larger secondary oocyte that has the potential to be released and fertilized, and a smaller cell known as the first polar body that will disintegrate.
Ultimately, even though up to four cells may be produced from the meiotic divisions involved in oogenesis, only one survives as a fertilizable mature egg. The rest of the cells, referred to as polar bodies, do not develop into mature gametes. This asymmetrical cell division ensures that the resulting secondary oocyte contains sufficient cytoplasm and organelles necessary in the event of fertilization.
A single initial oocyte usually results in the production of one mature egg through the process of oogenesis.
