Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells.

WebAug 6, 2024 · 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. In this example, a diploid body cell contains 2n = 4 chromosomes, 2 from mom and two from dad. WebSep 18, 2024 · Gametes, or reproductive cells, are produced in a special kind of cell division called meiosis. During this process the normal number of the cell's chromosomes is reduced by half. Each gamete ends up with a copy of one chromosome from each pair. Meiosis is a continuous process, but for convenience it is usually examined as a series …
