释义

Definition of gametogenesis in English:

gametogenesis

nounɡəˌmiːtə(ʊ)ˈdʒɛnɪsɪsɡəˌmidəˈdʒɛnəsəs
mass nounBiology
  • The process in which cells undergo meiosis to form gametes.

    Example sentencesExamples
    • Sporulation in single-celled eukaryotes such as yeasts is a morphogenetic process equivalent to gametogenesis, because an ascospore is a highly specialized cell and its formation is preceded by meiotic nuclear division.
    • Meiosis is the component of gametogenesis responsible for the segregation of homologous chromosomes into haploid gametes.
    • Homologous chromosomes are fully aligned at the pachytene stage, and germ cells survive to complete meiosis and gametogenesis with high efficiency.
    • Normally, the adult proximal germline contains germ cells undergoing gametogenesis and proliferation is restricted to the distalmost part of the adult gonad.
    • Males arise spontaneously through nondisjunction of the X chromosome during gametogenesis and the subsequent fusion with a normal gamete, yielding an XO individual.

Derivatives

  • gametogenic

  • adjective

    • Nevertheless, the studies carried out make no correlation between follicular components or acinus and gametogenic cycle stages.
      Example sentencesExamples
      • The final stages of gametogenic development, spawning activity, and major shell growth also take place during this low-salinity period.
      • Typically, the small-sized tubules are in an early gametogenic stage and the largest tubules are mature.
      • There are, however, important gametogenic events which are specific to multicellular organisms.
      • The cortex is the main functional area of the ovary and performs the gametogenic and endocrine functions.
  • gametogeny

  • noun
    Biology
    • After the second or third division, the schizonts invade further cells, where gametogeny, or sexual division, occurs.
