WebMeiosis ( / maɪˈoʊsɪs / ( listen); from Ancient Greek μείωσις (meíōsis) 'lessening', since it is a reductional division) [1] [2] is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four ...

WebMeiosis I is a type of cell division unique to germ cells, while meiosis II is similar to mitosis. Meiosis I, the first meiotic division, begins with prophase I. WebIn meiosis, a cell containing the diploid number of chromosomes is converted into four cells, each having the haploid number of chromosomes. In human cells undergoing meiosis, for instance, a cell containing 46 chromosomes yields four cells, each with 23 chromosomes. Meiosis occurs by a series of steps that resemble the steps of mitosis.

WebMeiosis sets the stage for Mendelian genetics. Students need to know that most of the genetics action occurs in the first meiotic division: homologous chromosomes pair up and align end-to-end (synapsis) in prophase I crossing over occurs between homologous chromosomes in prophase I, before chromosomes line up at the metaphase plate WebApr 13, 2024 · Meiosis is a type of cell division in sexually reproducing organisms that reduces the number of chromosomes in gametes (the sex cells, or egg and sperm).
