|
|
it creates identical daughter cells and mitosis does not.
|
|
|
it reduces the number of chromosomes by half whereas mitosis keeps the same number
|
|
|
meiosis and mitosis are not different at all
|
|
|
meiosis creates two daughter cells and mitosis creates four
|
Detailed explanation-1: -Mitosis creates two identical daughter cells that each contain the same number of chromosomes as their parent cell. In contrast, meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.
Detailed explanation-2: -Mitosis produces two genetically identical “daughter” cells from a single “parent” cell, whereas meiosis produces cells that are genetically unique from the parent and contain only half as much DNA. Most cells in the body regularly go through mitosis, but some do so more often than others.
Detailed explanation-3: -Meiosis is sometimes called “reduction division” because it reduces the number of chromosomes to half the normal number so that, when fusion of sperm and egg occurs, baby will have the correct number.
Detailed explanation-4: -The other type of cell division, meiosis, ensures that humans have the same number of chromosomes in each generation. It is a two-step process that reduces the chromosome number by half-from 46 to 23-to form sperm and egg cells.
Detailed explanation-5: -The goal of mitosis is to produce daughter cells that are genetically identical to their mothers, with not a single chromosome more or less. Meiosis, on the other hand, is used for just one purpose in the human body: the production of gametes-sex cells, or sperm and eggs.
