中期分裂

It's metaphase. You want to check it?

分裂中期你要确认下吗？

Red CPD bands were shown on eight pachytene bivalents, and 12 bands were shown on six pairs of mitotic metaphase chromosomes.

CPD 染色在8条粗线期染色体上显示出了10条红色的CPD 带纹，在6对有丝分裂中期染色体上显示出了12条CPD带纹。

FISH with the tomato 45S rDNA clone revealed very strong signal in the satellite on the short arm of chromosome 2 as well as weak signals in five CPD banded regions at pachytene or four pairs of CPD banded regions at metaphase.

用番茄的一个45S rDNA 克隆进行的荧光原位杂交，不仅在位于2号染色体短臂的随体上显示了强的杂交信号，而且在粗线期染色体的5个CPD带区或有丝分裂中期染色体的4对CPD带区显示了弱的杂交信号。

The CPD bands exhibited on mitotic metaphase chromosomes corresponded to the prominent bands exhibited on the pachytene chromosomes.

有丝分裂中期染色体上的CPD带纹与粗线期染色体上显要的带纹具有对应性。

Clinical featu res: 18-year-old female, 155 cm high, 45 kg weight, uterus: 22×18 ×17 mm, unclear bilateral ovaries, normal pudendum, breast

A： 中期G带图； B：异常染色体核型分析图； C：家系图； D：减数分裂四分体配对模式图。临床表现：女， 18岁，身高155 cm，体重45 kg，子宫大小22

The phenological phase of reduction division of pollen mother cells and the morphological character of flo-wer buds at reduction division stage were examined.

观察了苹果二倍体品种金帅和国光减数分裂中期Ⅰ染色体配对和构型，提出了进一步研究这一问题的设想。

Chromosome pairing behavior in meiosis of the hybrid F1 was carried out. Results showed that in an average , 1.25 rod bivalents were observed in one PMC, meiotic configuration was 2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25) and most of PMCs possessed 1～5 bivalens, indicating that the relatively high homeology was detected between the D genome of Ae.tauschii and the V genome of D.villosum. The morphological differences between F1 hybrids and their parents were significant. F1 plants were highly self-sterile, but partially self-fertile after treated by chromosome doubling technique.

对杂种F1花粉母细胞减数分裂中期Ⅰ染色体配对行为进行观察发现，"节节麦×簇毛麦"杂种F1平均每PMC有1.25个棒状二价体，染色体的平均构型为2n=14=11.49Ⅰ+1.25Ⅱ(Xta=1.25)，大部分被观察的细胞出现1～5个二价体，表明节节麦D染色体与簇毛麦V染色体间具有相对较高的部分同源配对， D和V染色体之间存在一定的部分同源性。F1植株高度自交不育，经染色体加倍处理后能够自交结实。

F1 hybrid has the morphological feature which is between the male and female parents and shoed strong heterosis, exuberant vitality, late ripe period and low rate of self-fertility. The average chromosome configuration of F1 in PMC MI was 18.58Ⅰ+18.59Ⅱ+0.085Ⅲ+0.028Ⅳ. At anphase Ⅰ in PMC, some laggard chromosomes arranged in equatorial plate. Micronucleus and a lot of abnormal cells can be observed at dyad, tetrad and microspore.

杂种F1形态特征介于双亲之间，具有较强的杂种优势，生长旺盛，熟期晚，自交结实率较低。F1花粉母细胞减数分裂中期Ⅰ平均染色体构型为18.58Ⅰ+18.59Ⅱ+0.085Ⅲ+0.028Ⅳ，PMC后期Ⅰ观察到部分落后染色体排列在赤道板上；二分体、四分体和小孢子时期，细胞内普遍观察到微核，且出现大量异形细胞。

The supercontinent of Pangea began to break apart in the Middle Jurassic. In the Late Jurassic the Central Atlantic Ocean was a narrow ocean separating Africa from eastern North America.

盘古大陆在侏罗世中期开始分裂，到了晚侏罗世，中央大西洋已经张裂成一狭窄的海洋，把北美与北美东部分隔开来。

Besides, terminal synapsis was observed to occur in the meiosis of spermatocytes based on the analysis of signal distribution of 5S rDNA on chromosomes obtained from testis.3. 18S rDNA and histone gene h3 were mapped to the chromosomes of C.

此外，通过对5S rDNA在精巢染色体上信号分布特征的观察，认为中国明对虾的同源染色体在第一次减数分裂中期可能发生了末端联会。3。

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。
