Meiosis is the process by which a diploid cell (2n) undergoes division and produces a haploid cell (n). The cells which undergo meiosis are the spermatozoa and the primitive oogonium which are the male and female gametes respectively.
Mitosis is the process by which the cell nucleus divides, resulting in daughter cells that contain the same amount of genetic material as the parent cell. Meiosis is a two-stage cell division in eukaryotes resulting in gametes with one-half the number of chromosomes in the parent cell. The ...
Meiosisis the process by whichgametes(sex cells) are generated in organisms thatreproduce sexually. Gametes are produced in male and femalegonadsand contain one-half the number ofchromosomesas the original cell. Newgenecombinations are introduced in a population through thegenetic recombinationthat occur...
In humans, meiosis isthe process by which sperm cells and egg cells are produced. In the male, meiosis takes place after puberty. Diploid cells within the testes undergo meiosis to produce haploid sperm cells with 23 chromosomes. ... Fertilization restores the diploid number of chromosomes. ...
meiosis的用法和例句: 1. So, meiosis is the process by which a cell divides and splits up the number of chromosomes. 减数 是细胞 和染色体数减半的过程 以上参考资料就是本英汉词典详细汇总的单词meiosis的翻译英语含义,如有错漏请向我们提供反馈意见。
In biology, meiosis is the process by which one diploid eukaryotic cell divides to generate four haploid cells often called gametes. Meiosis isessential for sexual reproductionand therefore occurs in all eukaryotes (including single-celled organisms) that reproduce sexually. ...
Meiosis is the process where 4 genetically unique haploid daughter cells are produced. These are produced in the sexual organs, creating sperm in men and oocytes in females. During meiosis I, homologous chromosomes are split apart, while in meiosis ...
meiosis (mīŏˈsĭs), process of nuclear division in a living cell by which the number of chromosomes is reduced to half the original number. Meiosis occurs only in the process of gametogenesis, i.e., when the gametes, or sex cells (ovum and sperm), are being formed. Because fertil...
The first known use of meiosis was in 1550 meiosis儿童词典英英释义 meiosisnoun the process by which the number of chromosomes in a cell that produces sex cells is reduced to one half and that involves a reduction division in which one of each pair of homologous chromosomes passes to each dau...
1.part of the process of gamete formation in sexual reproduction consisting of chromosome conjugation and two cell divisions after which the chromosome number is reduced by half. Comparemitosis. 2.expressive understatement, esp. litotes. [1580–90; < Greekmeíōsisa lessening =meiō-,variant s. ...
