Mitosis and Meiosis
Mitosis
Mitosis is a type of cell division in which one cell (the mother) divides to produce two new cells (the daughters) that are genetically identical to itself. Mitosis is the way multicellular organisms grow and repair tissue. It is also how organisms reproduce asexually.
Mitosis
Cell division for growth , repair and for some organisms asexual reproduction.
2 daughter cells are produced which are genetically identical to each other.
Phases of Mitosis
Interphase (resting between divisions), Prophase, Metaphase, Anaphase and Telophase (Cytokinesis).

Meiosis
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females. During meiosis one cell divides twice to form four daughter cells. These daughter are genetically different to each other
Meiosis
Stages of Meiosis followed that create 4 daughter cells each containing the haploid(n) number of Chromosomes.
Chromosome combinations
When gametes are produced (by meiosis) in humans, the paired homologous chromosomes line up (Metaphase I) and separate during Anaphase I. Which chromosome from each of the 23 homologous pairs of both parents is inherited is a matter of chance. There are 8,324,608 possible combinations of 23 chromosome pairs (223). As a result, two gametes virtually never have exactly the same combination of chromosomes.
Meiosis
Cell division that results in the production of gametes
Meiosis
4 gametes(daughter cells) are produced as a result of meiosis. Each gamete contains half(n) the chromosome n umber of the parent cell. each gamete is genetically different from the other.
