MICROANATOMY

Detailed explanation-1: -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-2: -Most of the cytoplasm is retained by the mature egg (ovum), and a second polar body receives little more than a haploid nucleus. Thus, oogenic meiosis conserves the volume of oocyte cytoplasm in a single cell rather than splitting it equally among four progeny.

Detailed explanation-3: -Oogenesis in the female results in one functional gamete-the ovum, or egg-whereas spermatogenesis in males results in four functional gametes.
