if I'm not mistaken I'm pretty sure its that sperm cells and the egg. (gamete's)
each have around 23 chromosomes each. and a skin cell already has 46 chromosomes.
so mitosis wouldn't be able to happen.
well at least that's what i think.
Sex cells need ginetic variation in order to have the many outcomes that it creates and so we are notall exact copies of eachother. Mitosis is a cell making an exact copy of itself so the sex cells would
1.) cause us to all look the same and
2.) double the number of chromosomes each generation because the two would need to combine.
Meiosis goes through mitosis twice and includes crossing over and such to create, in the end, 4 cells each unique for every one cell it starts with.
Mitosis creates daughter cells with the same chromosome count as their parent, however meiosis daughter cells have half the number of chromosomes as their parent. This is because if two reproductive cells (formed by meiosis) meet, each will have half the chromosomes needed, adding up to 46, enough to make a new cell. If the two reproductive cells already had a full chromosome count met, they would combine to make a cell with double the chromosome count needed, horribly mutating it. Imagine that...
Hope this helps! Recommend me. ;o
Also because you were adopted.
Because reproductive cells generally need to have only half of the number of chromosomes that normal cells have. Therefore, they are formed by meiosis (splitting of the cell).
Sex cells must be haploid so they can combine to form a diploid zygote.
Mitosis splits a diploid into two diploid, so a diploid must use meiosis to become haploid.
because mitosis makes a duplicate cell & it would have too many chromosomes. meiosis makes sex cells
Daughter cells are produced in both meiosis and mitosis. The difference is daughter cells are 2N in mitosis and ultimately 1N in meiosis.
POOPY is my favorite food
because they are germ cells
Humans use both- mitosis to grow, meiosis to form sex cells for reproduction.
The order would be: Meiosis -> sex cells -> fertilization -> zygote -> mitosis Meiosis creates sex cells, called gametes, which combine during fertilization to create a zygote. The zygote then undergoes mitosis.
two because in mitosis the cell divides only once so the two new nuclei form and forms two sex cells.
Somatic cells or body cells perform mitosis.
Hi, Mitosis produces gametes that are sex cells. Mitosis produces 2 identical cells.
mitosis= body cells or somatic cells Meiosis= sex cells or germ cells
mitosis is for cell division. meiosois is used when sex cells split to form the cells that are for the baby....
Mitosis is the form of cell division that most eukaryotic cells undergo. In humans, all somatic (non-sex) cells use mitosis to divide. Sex-cells use meiosis instead of mitosis.
Humans use both- mitosis to grow, meiosis to form sex cells for reproduction.
Your "germ" (or sex, but I prefer germ) cells undergo mitosis to create more diploids, but then they undergo Meiosis I to form a haploid. In boys, the germ cells will undergo Meiosis II to form their complete germ cells. In girls, the cell will only complete Meiosis II if the egg is fertilized. So the answer is sort of yes... the diploids will undergo Mitosis, but to actually get germ cells... they must undergo Meiosis.

Body cells. Meiosis deals with sex cells

No. Meiosis makes sex cells.
meiosis is where sex cells are made -there are 8 steps in meiosis mitosis is where the nucleus divides -there are 4 steps in mitosis they both make chromosomes
Cells in the body, apart from the sex cells, reproduce by mitosis, a form of asexual reproduction where the chromosomes are identical in both the parent and the daughter cells.
