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.
Spermatogenesis 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.
Two examples of gametogenesis?
Gametogenesis is defined as the production of gametes, or sex cells. The two examples would be spermatogenesis (production of sperm in males) and oogenesis (production of eggs in females.)

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.
The term for the production of gametes by means of meiosis?
The term for the production of gametes by means of meiosis is gametogenesis. Meiosis reduces the number of chromosomes by half, making possible the combination of two gametes to form a new individual.
What is called the process of formation of gametes?
The process of formation of gametes is called gametogenesis. It involves a series of cell divisions and differentiations that ultimately produce haploid gametes (sperm and egg) with half the number of chromosomes of a normal body cell.
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 is process of forming male gametes called?
The process of forming male gametes is called spermatogenesis. It involves the production and maturation of sperm cells in the testes through a series of cell divisions and differentiation steps.
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.

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.
The formation of the male sex cells or sperm is called a what?
The formation of male sex cells or sperm is called spermatogenesis. During spermatogenesis, specialized cells in the testes undergo a series of divisions and differentiations to produce mature sperm cells.
What is the difference between spermatogenesis and oogenesis?
Spermatogenesis takes place in the testes of males, oogenesis takes place in the ovary of the females.Spermatogenesis produces small, motile spermatozoa whereas in oogenesis the ovum is spherical, not motile and is much larger with more food reserves and cytoplasm.Spermatogenesis involves a metamorphosis stage called spermiogenesis, in oogenesis there is no metamorphosis stage.In spermatogenesis, 4 gametes are produced from each meiotic division, whereas in oogenesis there is only 1 gamete produced from each division as the unequal cytokinesis leads to the formation of polar bodies.Spermatogenesis occurs in males (human males) continuously from puberty to death whereas oogenesis starts in females in the fetal period. It takes 70 days for sperm to be produced in males.In oogenesis, the development of the oocyte is arrested at prophase I of meiosis until puberty, and then stops at metaphase II of meiosis until fertilization, where the meiotic division is finally completed. In males meiosis occurs continuouslyThe hormones in the 2 processes have different effects - in oogenesis, FSH is responsible for the choice of the primary oocyte and causes the cells of the membrana granulosa to proliferate to form the theca interna which secretes oestrogen, and the theca externa. LH in females stimulates ovulation and the maturation of the Graafian follicle. In males, on the other hand, FSH increases the activity of the Sertoli cells which are involved in spermiogenesis (the metamorphosis stage of spermatogenesis). LH in males stimulates the Leydig cells to secrete testosterone.
Summarize the major characteristics of spermatogenesis and oogenesis?
Spermatogenesis is the process by which diploid cells in the testes undergo division and differentiation to form haploid sperm cells. It involves mitosis, meiosis, and cellular differentiation to produce four functional sperm cells. On the other hand, oogenesis is the process by which diploid cells in the ovaries develop into mature egg cells. Unlike spermatogenesis, oogenesis only produces one mature egg cell per cycle and involves unequal division of cytoplasm between the resulting cells.
