Mitosis+vs.+Meiosis

=What is Mitosis?= Mitosis: A stage in a cell cycle where cellular reproduction happens by dividing into two identical daughter cells that are genetically same as the parent cell. There are same number of genes and chromosomes in the nuclei of daughter cells.



=What is Meiosis?=

Meiosis: Special cellular division that produces four daughter cells with different combinations of genes and 50% of chromosomes of the parent cell.



= = =Meiosis vs Mitosis=
 * || ** Meiosis ** || ** Mitosis ** ||
 * Produces: || Four haploid daughter cells || Two diploid daughter cells ||
 * Steps: || The steps of meiosis are Interphase, Prophase I, Metaphase I, Anaphase I, Telophase I, Prophase II, Metaphase II, Anaphase II and Telophase II. || The steps of mitosis are Interphase, Prophase, Metaphase, Anaphase, Telophase and Cytokinesis ||
 * Discovered by: || Oscar Hertwig || Walther Flemming ||
 * Genetically: || Different || Identical ||
 * Cytokenesis: || Occurs in Telophase I & Telohpase II || Occurs in Telophase ||
 * Number of Divisions: || 2 || 1 ||
 * Pairing of Homologues: || Yes || No ||
 * Type of Reproduction: || Sexual || Asexual ||
 * Function: || Sexual reproduction || Cellular Reproduction & general growth and repair of the body ||
 * Chromosome Number: || Reduced by half || Remains the same ||
 * Karyokenesis: || Occurs in Interphase I || Occurs in Interphase ||
 * Centromeres Split: || The centromeres do not separate during anaphase I, but during anaphase II || The centromeres split during Anaphase ||
 * Occurrence of Crossing Over: || Yes, Mixing of chromosomes (synapse) || No ||
 * Occurs in: || Humans, animals, plants, fungi || All organisms ||
 * Number of Daughter Cells Produced: || 4 haploid cells || 2 diploid cells ||
 * Creates: || Sex cells only: Female egg cells or Male sperm cells || Makes everything other than sex cells ||
 * Definition: || A type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes in a diploid cell. || A process of asexual reproduction in which the cell divides in two producing a replica, with an equal number of chromosomes in haploid cell ||
 * Similarities: |||| Chromosomes Duplicate ||
 * ^  |||| Relative Positioning of chromosomes same at each stage ||
