减数的

However, accidental changes in DNA methylation can be transmitted through mitosis or meiosis, leading to epiallelic variation.

但是，DNA甲基化的意外变化能够通过有丝分裂或减数分裂，导致表观变异。

The primary sporogenous cells divided into the second sporogenous cells which would turn into microspore mother cells in a microsporangium. The cytokinesis in meiosis of the microspore mother cells was of modified simultaneous type, forming the decussate, isobilateral or T-shaped tetrads.

初生造孢细胞分裂形成次生造孢细胞，次生造孢细胞再转化为小孢子母细胞，小孢子母细胞减数分裂的胞质分裂为修饰性同时型，四分体排列方式为交叉型、对称型或"T"型，成熟花粉粒二细胞型，开花时散出。

If you subtract the difference from the minuend and get the subtracter, you're

方法二：从被减数里减去算出的差，看是不是等于减数。

However,the ratio ofunivalent misdivision was about 10 per cent.This wouldoffer the posibility to creat whole arm chromosometranslocation.

然而，发现在减数分裂时，单价体错分裂频率达到10%左右，为产生染色体整条臂的相互易位提供了可能。

Aneuspory The production of an unusual number of spores during meiosis of a spore mother cell.

异数孢子：在孢子母细胞减数分裂过程中产生不正常孢子数目的现象。

Small cell of the mother after the cytoplasm of simultaneous type, tetrad of epidermis, mature pollen of two cell types.

小孢子母细胞减数分裂后胞质分裂为同时型，四分体为四面体型排列，成熟的花粉粒为二细胞型。

Autopoly-ploids may arise from the fusion of diploid gametes that have resulted from the NONDISJUNCTION of chromosomes at meiosis.

同源多倍体通常可能来自在减数分裂过程中染色体不分离导致的二倍体融合。

It also led to the discovery in 1916 by Calvin Bridges of the phenomenon of nondisjunction, in which a chromosome pair fails to segregate during meiosis.

伴性遗传又导致了不分离现象的发现，即在减数分裂中，染色体对不分离。

Tetraploid organisms may arise by the fusion of two diploid gametes that have resulted from the nondisjunction of chromosomes at meiosis, or by nondisjunction of the chromoosomes during the mitotic division of a zygote.

四倍体的产生可能是由于两个二倍体配子发生融合，这种二倍体配子又是在减数分裂中染色体不发生分离而形成。四倍体也可能因为受精卵进行有丝分裂时染色单体未发生分离而形成。

Pachytene in MEIOSIS ,the stage in mid-prophaseⅠ that is characterized by the contraction of paired homologous chromosomes.

粗线期：减数第一次分裂前中期中的一个阶段，以配对同源染色体浓缩为特征。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
