Why does meiosis lead to significant genetic variational mitosis does not?

Meosis is a process of cell division where a diplod cell becomes four haploid cells resembling mitosis but the chromosomes are duplicated once in which gametocytes form gametes.They occur in genetic information in variation of female and male gametes.
In mitosis the nuclei of the diplod cells reproduce after chromosomes duplicate in four stages with two diploid cells formed with identical set of chromosomes with the cytoplasm also divides with the cells. They occur in somatic cells.

When does meiosis play a more significant role than mitosis?
Meiosis is the reproduction of the gametes or sex cells. So I'd go with meiosis.
Differences between mitosis and meiosis?
place of occurence ;mitosis= somatic cells | meiosis=gonadic cells crossing over;mitosis=does not occur | meiosis=occur during prophase of meiosis 1 to form tetrads number of daughter cell;mitosis=two | meiosis= four genetic variation;mitosis=no variation produced| meiosis=produces genetic variation genetic composition in daughter cell; mitosis=identical to the parent cell | meiosis= non identical to the parent cell and each other
What does meiosis introduce into the daughter cells that Mitosis does not?
variationvarietyMeiosis introduces genetic variation. Mitosis produces daughter cells that are identical to the parent cell. However, meiosis produces offspring with half the genetic material from each parent - and therefore much more diversity.
Why is it necessary for homologous to pair during meiosis and not desirable for them to pair in mitosis?
to cross over which results in the genetic recombination
How many cells do you end up with after mitosis and meiosis?
After mitosis you have two cells and after meiosis you have 4 cells.

Do mitosis and meiosis produce cells with the same amount of genetic information?
Meiosis cells have half the amount of genetic info as cells of mitosis.
What specific meiotic events contribute to meiosis leads to significant genetic variation while mitosis does not?
may be its genetical diffence

Which is responsible for genetic variation mitosis or meiosis?
Meiosis is responsible for genetic variation
Why are mitosis and mitosis similar?
Because they both result in the formantion of gametes; however there is no genetic variation in meiosis.
What type of cell division Mitosis or meiosis is important in genetic study?
Both
When comparing the processes of meiosis and mitosis we find that they?
start out similarly, but end up differently.
Why meiosis is called modified mitosis?
Meiosis is very similar to mitosis. Meiosis produces two "half-cells" after the first cell division. Mitosis, however produces two fully genetically capable cells. After mitosis, the cell products can reproduce by themselves. Meiosis is a "modified" version of mitosis, meant for genetic diversity. Mitosis probably existed way before meiosis, simply because it is easier to execute. Meiosis produces what is called a gamete. These gametes, or 'sex cells' cannot reproduce by themselves. These half-cells are meant to be combined with the complementary gamete (egg with sperm) to maximize genetic diversity and promote evolution. Mitosis is the simplified version of meiosis, and meiosis is the "modified" mitosis. You often find mitosis in simple organisms, meant solely for reproduction purposes. Meiosis is more common in evolutionarily advanced organisms, such as mammals.
Which happens first mitosis or cell division?
Mitosis was first discovered and meiosis evolved out of mitosis. Mitosis stands for the first division of a cell into two genetic identically cells. Meiosis stands for two divisions into four genetic different cells.
What does meiosis introduce into the daughter cells that Mitosis does not?
variationvarietyMeiosis introduces genetic variation. Mitosis produces daughter cells that are identical to the parent cell. However, meiosis produces offspring with half the genetic material from each parent - and therefore much more diversity.
How do genetic contents of cells resulting from mitosis different from meiosis?
The four daughter cells resulting from meiosis are haploid and genetically distinct. The daughter cells resulting from mitosis are diploid and identical to the parent cell.
