减数分裂

In organisms showing ALTERNATION OF GENERATIONS, the gametes may be produced by mitosis in the haploid generation, or by meiosis in the diploid generation and give rise directly to gametes or gamete-producing cells.

在表现出明显世代交替的生物体中，配子可能是由单倍体世代发生有丝分裂产生，亦可由二倍体世代减数分裂直接产生配子体或配子母细胞。

The mitotic error rate in cleavage stage embryos was proven to be higher than the meiotic aneuploidy rate and as a consequence, the genome of a single blastomere is not representative for the genome of the other cells of the embryo.

在卵裂期胚胎这种有丝分裂的错误率被证明是高于减数分裂的非整倍体错误率，因此，单个卵裂球的基因不能代表其他胚胎细胞的基因组。

Meiosis, which occurs only in the formation of gametes, is a specialized form of cell division.

仅仅发生在配子形成中的减数分裂是一种特殊形式的有丝分裂。

仅仅发生在配子形成中的减数分裂是一种特殊形式的细胞分裂。

Chromatid One of a pair of replicated chromosomes found during the prophase and metaphase stages of mitosis and meiosis.

染色单体：在有丝分裂和减数分裂的前期和中期一对已经复制了的染色体中的一个。

Sister chromatid cohesion is fundamental to the faithful transmission of chromosomes during both meiosis and mitosis.

姐妹染色单体粘连是有丝分裂和减数分裂时染色体忠实分离的基础。

To accomplish this, sister chromatids must segregate together during the first meiotic division , which requires that sister chromatid cohesion persists at centromeres.

实现减数分裂，姐妹染色体必须在第一次分裂联会，这过程姐妹染色体在着丝粒结合。

Meiosis is the cell division to form gametes that have half the chromosome number of the parent cell.

减数分裂是一种形成只有半数染色体数目的配子的细胞分裂。

Diakinesis The last stage of the PROPHASE in the first division of MEIOSIS.

终变期：减数分裂第一次分裂前期中的最后一个阶段。

These mainly involve the periodic change of ribosome den- sity,the dedifferentiation and redifferentiation of both plastid and mitochondrion during the process of meiosis.

在这个过程中，小抱子母细胞经减数分裂产生大致相同的4个减数抱子，并逐渐发育成雄配子体。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.

镀锌钢托盘多用于出口，替代木托盘，免薰蒸，符合欧盟、北美各国对出口货物包装材料的法令要求；喷涂钢托盘适用于重载上货架之用，托盘表面根据需要制作成平板状、波纹状及间隔形式，满足不同的使用要求。
