How many sperm cells are formed at the end of spermatogenesis?

The process of spermatogenesis involves multiple steps.\nwithin the wall of the seminiferous tubules, spermatigonium will split via mitosis. Each complete spermatogonium, aka primary spermatocyte will undergo meiosis. So one cell undergoes meiosis and produces 2 secondary spermatocytes. But the process is not yet comlete. These secondary spermatocytes must undergo a second meiotic division resulting in 4 spermatids which mature into sperm. \n\nSo for every starter cell, 4 sperms cells are formed at the end of this process.

when the egg and sperm unites theres fertilization. after that unity, the egg and sperm will become multiples cells which would eventually become a fetus and growing and growing to become a baby. that baby will then come out either from your mother's abdomen (c-section) or vagina (normal delivery)

46 chromosomes or 23 pairs of chromosomes per cell, consisting of 22 pairs of autosomes, and two sex chromosomes; considering the body has over a trillion cells...\n That is basically 46,000,000,000,000 chromosomes!\nThere are some rare cases when there is an extra chromosome(ex: Downsyndrome) or one less chromosome in each cell.

First of all, gametes are produced only through meiosis and the location only occurs in the gonads(testes or ovaries). \n\nMitosis occurs all over the body for growth and repair while mitosis is for reproduction. Mitosis undergoes only one cell division to produce two identical daughter cells. Meiosis has 2 cell divisions producing 4 haploid daughter cells with mixed genes by synapsis and crossing over.

This sounds like a homework question. Think about it this way: what does diploid mean, and what does haploid mean? What has to happen for a gamete to form? How many chromosomes in a haploid gamete as opposed to a diploid somatic cell? What happens at fertilization? How many chromosomes would be in a fertilized zygote if you count up what was in each gamete?\n\nHints: a gamete is an egg or sperm; a somatic cell is any cell that is not a gamete; a zygote is what is formed when egg and sperm combine in fertilization. Post again if you're still stuck.

The male reproductive organ produces sperms (male gametes).These are short lived,temperature sensitive,acid sensitive.The body temp.(normal)is 37^c.The sperms get destroyed at this temp.They require temp. 2^c less than body temp for survival and normal functioning.Hence, testes are located outside the body.

Children are pretty smart these days. To make a baby you need a sperm cell and an egg cell. The sperm cell comes from the daddy and the egg cell comes from the mommy. When the sperm and egg meet, they make a tiny baby that is smaller than a grain of salt. The baby grows in the mommy's tummy for nine months. Then the baby is ready to come out.

On average, the ejaculate of a human male contains 10,000,000 sperm.  10,000 will make it to the uterus.  100 will make it to the fallopian tube.  10 will make it past the zona pellucida (which surrounds the egg).  1 will fertalize the egg.  So the chances of any given sperm fertilizing an egg is about 1 in 10,000,000 (i.e. 1 in 10 million).  However, that's assuming the sperm are released inside a woman's vigina and she's not using any form of birth control.  If you're talking about the general population of all sperm it's a whole lot lower.

Meiosis: -- One cell becomes 4 cells--There are 4 new "daughter" cells. Each new gamete cell contains only one-half of the number of chromosomes of the parent cell. Each sex cell goes through the division process twice in order to have the correct number of cells, and the correct chromosomal information.\n\nMitosis: -- One cell becomes two cells-- The new "daughter" cell has exactly the same number of chromosomes and information as the "parent" cell. 1 cell divides and becomes 2 cells.

Meiosis is the type of cell division by which germ cells (eggs and sperm) are produced. Meiosis involves a reduction in the amount of genetic material

If the total number of cells you finish with at the end of what I assume is mitosis is 36, then you began with 18 cells, which I suppose is 50%.  Is that at all what you are asking?

sex cells. they only have half the nomal number of chromosomes.

Much like the spermatogensis question, this process involves multiple steps.\n\nYou start with 1 oogonium. It can mitotically divide to produce multiple primary oocytes. Taking 1 oocyte, it will undergo meiosis producing a polar bosy and the secondary oocyte. A second meiotic division occurs producing the oocyte and another polar body.\n\nSo, 1 original cell produces 1 oocyte plus 2 polar bodies.\n\nIn some species the polar bodies undergo division as well.

Meiosis only happens in sex cells. Mitosis happens in all other cells. When mitosis happens the cell splits in two. Meiosis forms 4 cells, in females only one is an egg, in males all four are sperm. Meiosis goes twice through every stage, ie   metaphase.

B. Secondary spermatocytes... spermatids are the product of the meiosis II which under go metamorphosis to become spermatozoa, but they don't go through meiosis again

1- Meiosis happens in stem cells that give rise to gametes (sex cells). \nMitosis happens in all other cells.\nIn women every month only one stem cell goes through meiosis forming 4 haploid cells. In men many cells go through meiosis everyday.\nEvery other cell in body goes through mitosis in a daily basis to replace old and dead cell.\n2- Before cell replication starts.\n3- At the end of the prophase (in case of meiosis, end of the prophase 1)\n4- Mitosis: diploid cells; Meiosis: haploid cells\n5- Every thing but cell division: the cell obtain nutrients and when it gets close to cell division, it will duplicate its DNA and other organelles.
