Mitosis is a process of cell duplication, or reproduction, during which one cell gives rise to two genetically identical daughter cells. Strictly applied, the term mitosis is used to describe the duplication and distribution of chromosomes, the structures that carry the genetic information.
Meiosis is a special type of cell division that reduces the chromosome number by half, creating four haploid cells, each genetically distinct from the parent cell that gave rise to them. This process occurs in all sexually reproducing single-celled and multicellular eukaryotes, including animals, plants, and fungi. Errors in meiosis resulting in aneuploidy are the leading known cause of miscarriage and the most frequent genetic cause of developmental disabilities
Difference between Mitosis and Meiosis
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Below we highlight the keys differences and similarities between the two types of cell division.
|Meaning||Mitosis is the process of cell division which occurs in all types of cells (excluding sex cells), with the purpose of the asexual reproduction or the vegetative growth.||Meiosis is the process occurs in the specialized type of cell called as meiocytes, which supports the sexual reproduction by the gametogenesis.|
|Discovered by||Walther Flemming.||Oscar Hertwig.|
|Occurs in||Somatic cells.||Germ cells.|
|Type of Reproduction||Asexual||Sexual|
|Involvement||Involves one cell division||Involves two successive cell divisions|
|Results||Results in two daughter cells||Results in four daughter cells|
|Identification||Daughter cells are genetically identical||Daughter cells are genetically different|
|Exception||Occurs in all organisms except viruses||Occurs only in animals, plants and fungi|
