减数分裂

They are two different axial structures which are formed sequentially in meiotic chromosomes.

它们是减数分裂染色体中先后出出的两种不同的轴结构。

The sperm must not have undergone meiotic division...

精液不能已经遭遇减数分裂的区分。。。

Since crossing over can occur during the first meiotic division, it does allow for some genetic variation in the offspring.

在第一次减数分裂的过程中可以发生交换现象，因而在后代中有遗传变化。

The in vitro meiotic process and developmental competence of buffalo oocytes from different size follicles was investigated.

探讨了不同大小水牛卵泡卵母细胞体外成熟过程中的减数分裂进程及其胚胎发育潜能。

Triggers the egg's final meiotic reduction divisions.

融合也触发了最后的减数分裂。

In addition, the journal publishes key papers on chromosome aberrations in somatic, meiotic and malignant cells of man and other animals.

此外， 该刊还发表体细胞染色体失常，细胞减数分裂和人体与其他动物恶性细胞的论文。

The chiasmata observed during the later stages of the meiotic prophase are cytological evidence of earlier cross-over events.

在减数分裂前期末所看到的交叉是在这以前发生了互换事件的细胞学证据。

Under imitated daily field microclimatic conditions for heat stress, the rice cultivar "Jinyou63"(which is a hybrid rice combination) was treated with a consecutive 3-day heat stress during meiosis in phytotron. Anther and pollen tissues at different development stages after subjected to heat stress were sampled and analyzed for transverse abnormalities.

本研究模拟田间典型灾害天气条件，在人工气候箱内对杂交水稻&金优63&花粉母细胞减数分裂期进行连续3 d的热害胁迫处理，对处理后不同发育时期的花药组织取样切片观察，从组织、细胞水平探讨水稻受高温胁迫后花药可能出现的早期异常特征。

In the offsprings of the aneuploids (P3) with 41~44 chromosomes, there are four types of plants with 29~32 chromosomes. Except the plant with 29 chromosomes, others which appeared abnormal meiosis behavior and poor pollen fertility are mixoploid.

在染色体数为44与41的两种超倍体（P3群体）后代，鉴定出具有29~32条染色体的4种非整倍体，除染色体数为29的植株外，其余均为混倍体，它们的减数分裂异常，花粉育性低。

Confocal laser scanning microscopy used to localize the hsp70 protein in oocytes and embryos revealed that the distribution of hsp70 in the ooplasm of immature and mature oocytes is unaffected by exposure to decreased or elevated temperatures and that this protein was closely associated with the meiotic spindle indicating its possible role in stabilizing this structure, hi eight-cell embryos derived under control conditions, hsp70 was evenly distributed in the cytoplasm but appeared as aggregates in some embryos exposed to elevated temperature.

此蛋白均匀地分布在两种细胞的胞浆中。此形态特点与减数分裂期纺缍体有关，由此表明hsp70在中期Ⅱ期，具有稳定这种结构的作用。在对照组8细胞胚中，hsp70均匀地分布在胞浆中，而在处理组一些胚胎内，hsp70则发生凝集。

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.
