WebbMeiosis is a process that creates sex cells (gametes) with half the number of chromosomes of the parent cell. Meiosis has two stages: meiosis I and meiosis II. In meiosis I, homologous chromosomes pair up and exchange genetic material (crossing over). In meiosis II, sister chromatids separate, creating four haploid cells.

WebbMeiosis is the specialized type of cell division by which sexual organisms produce gametes. In most organisms, meiosis produces haploid gametes from diploid precursor cells. Meiosis halves the chromosome number via two successive rounds of chromosome segregation that follow a single round of chromosome replication.
