four times as great
Yes, both oogenesis (egg production) and spermatogenesis (sperm production) utilize meiosis to produce haploid gametes, or gametes with half the normal amount of genetic material.
Oogenesis is the formation of the ovum, and spermatogenesis is the formation of the sperm. These two processes are similar as they are both formed by meiosis, (reduction division). Meiosis is the process of cell division where one mother cell will create four daughter cells with half the amount of genetic information. Or in other words, oogenesis and spermatogenesis are creating gametes.
It's four.
That would be called pregenant in most languages.
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.
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.)

the formation of sex cells GAMETES: sperm or egg cells Gamete formation: gametogenesis Sperm formation: spermatogenesis Egg formation: oogenesis
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.
It is still called meiosis, except that instead of an egg you end up with a sperm cell.
It's four.
spermatogenesis
meiosis is the process; males produce four haploid gametes (sperm) while in females only a single haploid gamete (egg) is produced. The other three cells (polar bodies) fail to mature and die.
That would be called pregenant in most languages.
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.
Oogenesis (misspelled as oogenesis) is the creation of an egg cell. The benefit of uneven production of gametes in oogenesis is one haploid cell gets the majority of the nutrients.
