  • the form of cell division occurring in specialized tissues in the testes and ovary that leads to the production of gametes (only have half of genetic material, in humans gametes have 23 chromosomes).

  • the preparation and maturation of a cell, whereby the chromosome number is reduced by one half (reduction division)

  • the type of cell division occurring in the germ cells by which gametes containing the haploid chromosome number are produced from diploid cells

  • The reduction division process by which haploid gametes and spores are formed, consisting of a single duplication of the genetic material followed by two mitotic divisions.
  • Meiosis is the formation of egg and sperm cells. In sexually reproducing organisms, body cells are diploid, meaning they contain two sets of chromosomes (one set from each parent). To maintain this state, the egg and sperm that unite during fertilization must be haploid, meaning they each contain a single set of chromosomes. During meiosis, diploid cells undergo DNA replication, followed by two rounds of cell division, producing four haploid sex cells.
