reduction division

Noun
  1. (genetics) cell division that produces reproductive cells in sexually reproducing organisms;
    The nucleus divides into four nuclei each containing half the chromosome number (leading to gametes in animals and spores in plants) (synset 113533928)
    referred to in: genetic science, genetics - the branch of biology that studies heredity and variation in organisms
    is a type of: cell division, cellular division - the process in reproduction and growth by which a cell divides to form daughter cells
    subtypes: nondisjunction - meiosis in which there is a failure of paired homologous chromosomes to separate; results in an abnormal number of chromosomes in the daughter cells
    has:
    • anaphase - the stage of meiosis or mitosis when chromosomes move toward opposite ends of the nuclear spindle
    • cytokinesis - organic process consisting of the division of the cytoplasm of a cell following karyokinesis bringing about the separation into two daughter cells
    • karyokinesis - organic process consisting of the division of the nucleus of a cell during mitosis or meiosis
    • metaphase - the second stage of meiosis
    • prophase - the first stage of meiosis
    • segregation - (genetics) the separation of paired alleles during meiosis so that members of each pair of alleles appear in different gametes
    • telophase - the final stage of meiosis when the chromosomes move toward opposite ends of the nuclear spindle
    same as: meiosis, miosis
