减数的

Under normal temperature, anthers of not fertility restoration stopped developing in the stage of archesporical cell; 1-2 comers of a few anther could differentiate and form archesporical cell, sporogenous cells and microspore mother cell, but microspore mother cell disintegrated on the first meiotic division.

常温下，未发生育性恢复的花药在孢原细胞期就停止发育；少数花药1~2个角隅处可分化形成孢原细胞，造孢细胞，花粉母细胞，但花粉母细胞在减数分裂的第一次分裂时解体。

But, there was no Ca(superscript 2+) precipitate in tapetal cells of Zhenshan 97B at the pollen mother cell stage and the meiosis stage and the Ca(superscript 2+) precipitates in tapetal cells mainly deposited in the disaggregated cytoplasm.

而保持系绒毡层细胞遮花粉母细胞时期和减数分裂时期细胞内没有Ca(上标 2+)沉淀；单核花粉时期绒毡层细胞内的Ca(上标 2+)沉淀主要分布在解体的细胞质内。

Terminalization The movement of chiasmata to the end of the bivalent arms, a process that may occur during late prophase I of meiosis.

交叉移端：发生在第一次减数分裂后期，染色体交叉向二价体染色体臂的末端移动的过程。

Observation of spontaneous occurrence of 2n pollen in a fewC itrusspec ies confirm ed the existence of unreduced pollen in them.

试验中初步观察了柑橘属部分品种的2n花粉自然发生情况，证实了柑橘属内未减数花粉的存在。

The female gametes with 21 chromosomes intended to be with stronger competitive ability for pollination. Successful backcross didn't depend on the unreduced female gametes from restitution division.

同时也证明，回交的成功并不取决于杂种F1通过重建分裂形成的未减数雌配子。

These results indicate that TGA treatment can accelerate GVBD in Xenopus oocytes, and GVBD of mouse oocytes at low dose.

在小鼠中卵母细胞中，低剂量的TGA也可加速第1次减数分裂的启动。

Chiasmata also help to hold homologs together until the start of anaphase, thus helping to ensure the correct distribution of chromosomes into the daughter nuclei.

交叉还可以使同源染色体始终在一起直到细胞减数分裂的后期，这样确保了染色体可以正确的进入子细胞。

Theoretical investigations suggested that the major bottleneck in narrowing down the confidence interval of QTL location is the limited number of informative meioses obtainable in most mapping populations of traditional methods.

理论研究表明，传统方法中作图群体有限的有效减数分裂数是进一步缩小QTL置信区间的一个瓶颈。

Methods: Twenty five patients with congenital missing of one or two incisors, 17 patients were treated with extraction, 5 patients were treated orthodontically and prostbodontically. 3 patients were treated with slenderizing to solve crowding and adjust median line and Bolton index.

25例先天缺失下颌个别前牙1～2颗的患者，其中17例采用减数方法进行矫治，5例集中间隙，结合修复进行治疗，3例结合邻面去釉、改变牙轴等手段解除拥挤，采用调整中线和Bolton指数的方法进行矫治。

Cytologic results showed that chromosome numbers of root cell are 2n 56, and 28 bivalents can be observed at PMC MI in the six 8x Trititrigia.

细胞学鉴定结果表明，6个八倍体小偃麦的根尖细胞染色体数目为2n=56，花粉母细胞减数分裂中期Ⅱ染色体构型为2n=28Ⅱ，具有高度的细胞学稳定性。

The labia have now been sutured together almost completely.The drains and the Foley catheter come out at the top.

此刻阴唇已经几乎完全的缝在一起了，排除多余淤血体液的管子和Foley导管从顶端冒出来。

To get the business done, I suggest we split the difference in price.

为了做成这笔生意，我建议我们在价格上大家各让一半。
