Process in which chromosomes are replicated and separated into two new identical nuclei For the type of cell division in sexually reproducing organisms used to produce gametes, see Meiosis.

3. Cell division - Wikipedia

   en.wikipedia.org/wiki/Cell_division

   Meiosis undergoes two divisions resulting in four haploid daughter cells. Homologous chromosomes are separated in the first division of meiosis, such that each daughter cell has one copy of each chromosome. These chromosomes have already been replicated and have two sister chromatids which are then separated during the second division of ...

4. Chromosome segregation - Wikipedia

   en.wikipedia.org/wiki/Chromosome_segregation

   During the phase of meiosis labeled “interphase s” in the meiosis diagram there is a round of DNA replication, so that each of the chromosomes initially present is now composed of two copies called chromatids. These chromosomes (paired chromatids) then pair with the homologous chromosome (also paired chromatids) present in the same nucleus ...

6. Cell cycle - Wikipedia

   en.wikipedia.org/wiki/Cell_cycle

   The eukaryotic cell cycle consists of four distinct phases: G 1 phase, S phase (synthesis), G 2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis). M phase is itself composed of two tightly coupled processes: mitosis, in which the cell's nucleus divides, and cytokinesis, in which the cell's cytoplasm and cell membrane divides forming two daughter cells.

7. Origin and function of meiosis - Wikipedia

   en.wikipedia.org/wiki/Origin_and_function_of_meiosis

   Mitosis is the normal process in eukaryotes for cell division; duplicating chromosomes and segregating one of the two copies into each of the two daughter cells, in contrast with meiosis. The mitosis theory states that meiosis evolved from mitosis. [9]

8. Cell (biology) - Wikipedia

   en.wikipedia.org/wiki/Cell_(biology)

   DNA replication, or the process of duplicating a cell's genome, [2] always happens when a cell divides through mitosis or binary fission. This occurs during the S phase of the cell cycle. In meiosis, the DNA is replicated only once, while the cell divides twice. DNA replication only occurs before meiosis I.

9. Human reproduction - Wikipedia

   en.wikipedia.org/wiki/Human_reproduction

   Male germ cells produced in the testes are able to perform special DNA repair processes during meiosis that act to repair DNA damages and to maintain the integrity of the genomes that are to be passed on to progeny. [7] Two of these DNA repair processes are homologous recombinational repair and non-homologous end joining. [7]
