Meiosis

Mitosis

Definition A type of cellular reproduction in which the number of chromosomes are reduced by half through the separation of homologous chromosomes, producing two haploid cells. A process of asexual reproduction in which the cell divides in two producing a replica, with an equal number of chromosomes in each resulting diploid cell.
Function Genetic diversity through sexual reproduction. Cellular reproduction and general growth and repair of the body.
Type of Reproduction Sexual Asexual
Occurs in Humans, animals, plants, fungi. All organisms.
Genetically Different Identical
Crossing Over Yes, mixing of chromosomes can occur. No, crossing over cannot occur.
Pairing of Homologs Yes No
Number of Divisions 2 1
Number of Daughter Cells produced 4 haploid cells 2 diploid cells
Chromosome Number Reduced by half. Remains the same.
Steps (Meiosis 1) Prophase I, Metaphase I, Anaphase I, Telophase I; (Meiosis 2) Prophase II, Metaphase II, Anaphase II and Telophase II. Prophase, Metaphase, Anaphase, Telophase.
Karyokinesis Occurs in Interphase I. Occurs in Interphase.
Cytokinesis Occurs in Telophase I and in Telophase II. Occurs in Telophase.
Centromeres Split The centromeres do not separate during anaphase I, but during anaphase II. The centromeres split during anaphase.
Creates Sex cells only: female egg cells or male sperm cells. Makes everything other than sex cells.
