Detailed explanation-1: -Female gametogenesis, also known as oogenesis, results in mature eggs. As a result of meiosis, only one egg is generated from four haploid cells.

Detailed explanation-2: -Oogenesis starts with the process of developing primary oocytes, which occurs via the transformation of oogonia into primary oocytes, a process called oocytogenesis. From one single oogonium, only one mature oocyte will rise, with 3 other cells called polar bodies.

Detailed explanation-3: -(b) Oogenesis or the formation of an ovum in human beings occurs by the process of meiosis. It results in the formation of four daughter cells which are unequal in size, i.e., a big mature ovum and 3 small polar bodies.

Detailed explanation-4: -The unequal cytoplasmic division ensures that the egg has ample nutrients. Thus, due to unequal division, only one egg develops during oogenesis compared to four sperms after meiotic division in oocytes and spermatocytes, respectively.

Detailed explanation-5: -In addition, whereas male meiosis results in the production of four sperm atazoa, a single oocyte is the sole viable product of female meiosis. Half of the chromosomes from each of the two meiotic divisions are ejected in nonviable structures known as the first and second polar bodies (Fig.
