meiosis

音標(biāo)發(fā)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.
幾十年來(lái)，傳統(tǒng)的理論認(rèn)為X染色體與減數(shù)分裂以及男性不育無(wú)關(guān)，因?yàn)樵谀行詼p數(shù)分裂過(guò)程中X染色體被沉默掉了。
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.
在所有的植物和許多原生生物中，減數(shù)分裂形成單倍體的細(xì)胞，這些細(xì)胞不經(jīng)過(guò)受精就分裂生長(zhǎng)，這就是孢子。
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，這些干細(xì)胞培育成熟，刺激它們進(jìn)入“成熟”過(guò)程，所附的作為精子標(biāo)志的染色體數(shù)量將在此過(guò)程中減半。

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

減數(shù)分裂
Meiosis and segregation in each individual can be directly and efficiently analyzed using RAPD markers.
各親本的染色體減數(shù)分裂狀況通過(guò)RAPD標(biāo)記的變化就可以直接體現(xiàn)出來(lái)。

減數(shù)分裂
Cytokinesis following meiosis was simultaneous, and tetrad was tetrahedral.
減數(shù)分裂中的胞質(zhì)分裂為同時(shí)型，四分體為四面體型。
成熟分裂
減數(shù)破裂
