Meiosis is a form of nuclear division that creates four haploid cells from one diploid cell. This process involves two rounds of cell division—meiosis I and meiosis II. Each round of cell division has four phases, which are similar to those in mitosis.
Meiosis is a process of two sequenced nuclear divisions neither of which is identical to mitosis. Meiosis always begins with a nucleus with two sets of chromosomes (a diploid nucleus) where each chromosome has two chromatids. Meiosis produces four nuclei each with one set of chromosomes (haploid nuclei) in which each chromosome has one chromatid.
Meiosis functions to reduce the number of chromosomes to one half. Each daughter cell that is produced will have one half as many chromosomes as the parent cell. Meiosis is part of the sexual process because gametes (sperm, eggs) have one half the chromosomes as diploid (2N) individuals.
21 paź 2023 · In biology, meiosis is the process where a cell replicates DNA once but divides twice, producing four cells that have half the genetic information of the original cell. It is how organisms produce gametes or sex cells, which are eggs in females and sperm in males.

Meiosis is a two-step process that consists of prophase, metaphase, anaphase, and telophase phases in each division, known as meiosis I and meiosis II.
Meiosis I, Meiosis II, and the maturation process each take approximately 16 days (48 days total). Males do not run out of sperm because mitosis precedes each meiosis. The diagram above shows that a spermatogonium divides by mitosis to produce a primary spermatocytes and a spermatogonium.
