meiosis    音标拼音: [mɑɪ'osəs]
n. [细胞核的] 减数分裂

[细胞核的] 减数分裂

meiosis
n 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) [synonym:
{meiosis}, {miosis}, {reduction division}]
2: understatement for rhetorical effect (especially when
expressing an affirmative by negating its contrary); "saying
`I was not a little upset' when you mean `I was very upset'
is an example of litotes" [synonym: {litotes}, {meiosis}]

  • Meiosis - Definition, Stages, Function and Purpose - Biology Dictionary
    Meiosis is the process in eukaryotic, sexually-reproducing animals that reduces the number of chromosomes in a cell before reproduction Many organisms package these cells into gametes, such as egg and sperm
  • Meiosis - Wikipedia
    Meiosis ( maɪˈoʊsɪs ⓘ) [a] is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, the sperm or egg cells It involves two rounds of division that ultimately result in four cells, each with only one copy of each chromosome (haploid)
  • Meiosis Definition, Diagram, Steps, and Function - Science Notes and . . .
    In biology, meiosis is the process where a cell replicates DNA once but divides twice, producing four cells that have half the genetic information of the original cell It is how organisms produce gametes or sex cells, which are eggs in females and sperm in males
  • Meiosis: Definition, Stages, Purpose with Diagram - Science Facts
    Meiosis is a cell division process where a single (parent) cell divides twice to produce four independent (daughter) cells, each having half the chromosomes as the original cell The term ‘meiosis’ came from the Greek word ‘meiosis’, meaning ‘lessening’
  • Meiosis: Phases, Stages, Applications with Diagram - Microbe Notes
    Meiosis is a type of cell division in sexually reproducing eukaryotes, resulting in four daughter cells (gametes), each of which has half the number of chromosomes as compared to the original diploid parent cell
  • Meiosis - National Human Genome Research Institute
    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) In humans, body (or somatic) cells are diploid, containing two sets of chromosomes (one from each parent)
  • Genetics, Meiosis - StatPearls - NCBI Bookshelf
    In the gametes, a different form of cell division occurs called “meiosis ” The outcome of meiosis is the creation of daughter cells, either sperm or egg cells, through reduction division which results in a haploid complement of chromosomes so that on joining with another sex cell at fertilization a new diploid chromosomal complement is
  • Meiosis - Function, Phases and Examples - Biology Online
    Meiosis is the process of four haploid cells formation from a parent diploid cell The steps of meiosis include 2 stages: meiosis I and meiosis II Meiosis 1 definition: the first stage in the meiotic division or the reduction division of the meiosis
  • Meiosis – Definition, Types, Steps, Importance, Examples
    Meiosis is a specialized form of cell division in sexually reproducing organisms that results in four non-identical haploid cells (gametes) from a single diploid parent cell, ensuring genetic diversity and maintaining consistent chromosome numbers across generations Types of Meiosis
  • 11. 1: The Process of Meiosis - Biology LibreTexts
    Meiosis is a series of events that arrange and separate chromosomes and chromatids into daughter cells During the interphases of meiosis, each chromosome is duplicated In meiosis, there are two rounds of nuclear division resulting in four nuclei and usually four daughter cells, each with half the number of chromosomes as the parent cell
