Difference between meiosis and mitosis?
What is meiosis and how does it differ from mitosis??

Meiosis is the process that creates sexual cells (gametes). They end up with half of the parent's DNA (half the chromosomes), so when it combines with another sexual cell, the resulting cell has the correct amount of DNA.
Meiosis occurs only in sexual organs (gonads).
Mitosis occurs through the body, whenever a cell replicates itself.
A little rhyme that helps you remember the difference: Mitosis happens in my toes.

Meiosis differs from mitosis because meiosis produces gametes, or sex cells, and makes 4 non- identical cells, because the chromatids in the cells have genetic diversity, because they cross over. Each cell ends up with 50% of the parent cell so that when the cell becomes fertilized, and becomes a zygote, the new cell will be 100%. Fertilization is when two sex cells combine. Some examples of these sex cells are egg, sperm and pollen (in plants).
The difference from mitosis is that mitosis produces two, identical eukaryotes, while meiosis produces four, non-identical sex cells.

"Mitosis" and "meiosis" are the processes that an organism prepares its cells for either asexual or sexual reproduction with the intention of ending up with a new organism.
Mitosis happens among cells that have no need to be different, and in fact, you want them to be the same from parent to child, like the division of skin, heart, stomach cells and so on. These cells are "autosomal." Specifically, "asexual" reproduction occurs when one organism (the parent) reproduces itself and produces an exact genetic copy (barring a mutation). Hydra, bacteria, and various single celled organisms procreate this way.
Meiosis is the production of sperm and egg cells. These cells are "gamete" cells. Each cell has to go through the division process twice, in order for the cell to end up with half the number of chromosomes that the parent cell started with. The cells then pass on genetic information to the offspring. This is a form of sexual reproduction, where one organism or cells reproduces by crossing with another organism or cell. Complex organisms like plants, insects, animals, and of course, people, reproduce this way. You end up with a daughter organism with an entirely different genetic sequence.

mitosis is where the cells of our body divide and then x by 2 for growth, repair and to replace cells- only two daughter cells are made and they are genetically the same each have 46 single chromosomes or 23 pairs
meiosis is the process in which our sex cells (gametes) are made they are made for reproductive purposes. this time 4 daughter cells are made which have no pairs just 23 single chromosomes.
so the differnce is the amount of chromosomes in the new cells formed by mitosis and the sex cells (gametes) made by meiosis are not genetically identical like the cells made by mitosis.
