The meiosis of egg formation is called?
The meiosis of egg formation is called oogenesis. During oogenesis, a primary oocyte undergoes two divisions to produce a single mature egg cell.
When 2nd polar body is extruded in human fertilization?
The second polar body is formed during the second meiotic division of the oocyte after fertilization, typically about 12-24 hours after the sperm has entered the egg. This second polar body contains half the genetic material of the previous oocyte and is eventually degraded.
Which organ is the site for spermatogenisis?
The scrotum needs to be able to move away from the body and closer to it depending on the need for heat. If your body is to hot the sack will expand and move away from your body and if it becomes to cold it will tighten and move into your body. This is all done with sperm production in mind as if its too hot or cold the sperm will die.
Sex cells divide using the process called?
Sex cells divide using the process called meiosis. During meiosis, a single cell divides twice to produce 4 cells with half the number of chromosomes. This is necessary for sexual reproduction as it ensures the offspring receives a unique combination of genetic material from each parent.
How many cells does spermatogenesis and oogenesis produce in humans how many chromosomes are in each?
spermatogenesis produces 4 sperm cells and oogenisis produces one ovum. Both have 23 chromosomes each
Meiosis in females is called?
Meiosis in females is called oogenesis. It is the process in which a diploid cell undergoes two rounds of cell division to produce one haploid egg cell and two polar bodies.
The meiosis of egg formation is called?
The meiosis of egg formation is called oogenesis. During oogenesis, a primary oocyte undergoes two divisions to produce a single mature egg cell.

How does oogenisis occur?
Oogenesis is the process by which female germ cells develop into mature eggs. It involves several stages, including the proliferation of germ cells, meiotic division to reduce chromosome number, and maturation of the egg. Oogenesis occurs in the ovaries and is critical for female reproductive function.
Cytoplasm divides unequally in meiosis during production of what?
The cytoplasm divides unequally during the production of ova (Oogenisis) This is because out of the four daughter cells created during meiosis, only one is needed to produce a single ovum, whearas in Spermatogenisis all four evolve to become sperm; thus the cytoplasm is divided equally.
Which organ is the site for spermatogenisis?

What is the process of gametogenesis?
multiplication phase, growth phase and maturatio phase
How do oogenesis and spermantogenesis differ?
In oogenesis after the first meiotic division one egg and one tiny cell are created. In Meiosis II the egg and three small cells are created. The three small cells are thrown away and the egg undergoes fertilization. In spermatogenesis after meiosis II four working sperms are ready to be used. There is only one usable cell created in oogenesis while in spermatogenesis four cells are created. the end result of oogenesis is only one viable cell while in sprematogenesis there are four.
