Spermatogenisis produces four gametes while oogenesis produces only one. Oogenesis produces one egg and three polar bodies (that immediately die off). Spermatogenisis produces four sperm that are al equally complex. The egg is the major part of the potential fertilized cell and it takes a lot of energy to make (think about it, all it needs to start dividing is a few extra chromosomes) and therefore most of the process's energy goes to the egg.

SteveSpermatogenesis produces four viable sperm cells per cycle, each with equal genetic material, while oogenesis results in one viable egg cell per cycle and three polar bodies with uneven genetic material due to asymmetric cell division. This difference in gamete numbers is due to the unequal division of cytoplasm during meiosis in oogenesis, leading to only one mature gamete being produced.

When compared with the number of gametes produced from a single primary sex cell during oogenesis the number of gametes produced from a single hman primary sex cell during spermatogenesis is usually w?
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.
How are oogenesis and spermatogenesis similar?
Oogenesis and spermatogenesis are both processes that involve the formation of gametes (eggs and sperm) through meiosis. Both processes start with diploid germ cells and result in the production of haploid gametes. Additionally, both processes involve several stages of cell division and maturation.
Does oogenesis involve meiosis?
Yes, oogenesis involves meiosis. In this process, a diploid cell undergoes two rounds of cell division to produce haploid eggs, which have half the number of chromosomes as the original cell.
What body system produces diploid and haploid cell by meiosis in humans?
The reproductive system in humans produces diploid cells through meiosis in the process of spermatogenesis (in males) and oogenesis (in females). These diploid cells eventually give rise to haploid gametes (sperm and eggs) which are involved in sexual reproduction.
Why testis and ovary are important in human reproduction?
Testis and ovary are important in human reproduction because they produce gametes (sperm and eggs), which are necessary for fertilization to occur. The testis produces sperm through the process of spermatogenesis, while the ovary produces eggs through the process of oogenesis. Without these gametes, fertilization and ultimately reproduction cannot take place.
