Meiosis is a mechanism of sexual cell division used to generate gametes, or sex cells, in reproductive organs. For example, generation of eggs in ovaries. By contrast, mitosis is an asexual method of cell division that occurs in all other cell types an is critical for processes such as cellular proliferation and differentiation during development. Meiosis generates 4 daughter cells, which are haploid and have half the number of chromosomes as their parent cells. This occurs through 2 cell divisions. Mitosis, however, only produces two daughter cells through a single cell division. These daugther cells are diploid and contain the same number of chromosomes as teh parent cell. Unlike mitosis, genetic reassortment can occur during prophase I in meiosis. This process inolves the crossing over of maternal and paternal chromosomes, resulting in an exchange of genetic material that leads to the genetic variance we observe with sexual reproduction.
