WebMeiosis [1] is a type of cell division that involves the reduction in the number of the parental chromosome by half and consequently the production of four haploid daughter cells.

WebApr 13, 2024 · Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm). In humans, body (or somatic) cells are diploid, containing two sets of chromosomes (one from each parent). To maintain this state, the egg and sperm that unite during fertilization must … Web5.2 Meiosis and Gametogenesis. Sexual reproduction requires fertilization, a union of two cells from two individual organisms. If those two cells each contain one set of chromosomes, then the resulting cell contains two sets of chromosomes. The number of sets of chromosomes in a cell is called its ploidy level.

WebDaughter cells process the same chromosome number as that of parent cell. 4. It is of short duration. 5. Daughter cells are similar to parent cell genetically. 6.
