meiosis

音标发音

For decades, conventional wisdom stated that the X chromosome had little to do with meiosis or infertility because the X chromosome is silenced during male meiosis.
几十年来，传统的理论认为X染色体与减数分裂以及男性不育无关，因为在男性减数分裂过程中X染色体被沉默掉了。
In all plants, and in many protists, meiosis results in the formation of haploid cells that can divide vegetatively without undergoing fertilization, referred to as spores.
在所有的植物和许多原生生物中，减数分裂形成单倍体的细胞，这些细胞不经过受精就分裂生长，这就是孢子。
Over four to six weeks, these cells developed and were prompted to undergo the process of "meiosis", which halved the number of chromosomes they carried - a hallmark of sperm.
四到六周之后，这些干细胞培育成熟，刺激它们进入“成熟”过程，所附的作为精子标志的染色体数量将在此过程中减半。

This should allow them to work out which of those genes are involved in suppressing meiosis.
ECONOMIST: Genetic engineering
Abolish meiosis and a plant may be able to produce viable seeds without having them fertilised.
ECONOMIST: Genetic engineering
And it may be possible to engineer a genetic switch, known as an inducible promoter, into the crop, along with the anti-meiosis genes.
ECONOMIST: Genetic engineering: No sex, please, we’re plants

the type of cell division that happens as part of reproduction (= the process of producing young animals or plants), in which one cell divides into four gametes (= reproductive cells), each with a different mixture of chromosomes and half the number contained in the original cell

a type of cell division in which a nucleus divides into four daughter nuclei, each containing half the chromosome number of the parent nucleus: occurs in all sexually reproducing organisms in which haploid gametes or spores are produced &rarrcompare mitosis

减数分裂
Meiosis and segregation in each individual can be directly and efficiently analyzed using RAPD markers.
各亲本的染色体减数分裂状况通过RAPD标记的变化就可以直接体现出来。

减数分裂
Cytokinesis following meiosis was simultaneous, and tetrad was tetrahedral.
减数分裂中的胞质分裂为同时型，四分体为四面体型。
成熟分裂
减数破裂
