The chromosome behavior of the meio sis at MI of the hybrids between every 2 of 5 OTE types and between vevry one of the hybrids with Tr.aestivum was observed.

通过八倍体小偃麦与普通小麦杂交，八倍体小偃麦相互间杂交，观察了杂种F1花粉母细胞减数分裂行为。

M-3-16 and baker's yeast BY-6 haploid strain without using melibiose was hybridized, 153 hybrids were identified.

将M-3-16与不利用蜜二糖的面包酵母BY-6单倍体进行杂交，共获得杂交株153株。

Amblycephala is composed of 13 metacentric chromosome pairs, 9 submetacentric chro-mosome pairs and 2 subtelocentric chromosome pairs, which can be expressed as 26m + 18sm+ 4st.

随着鱼类杂交育种研究的深人，染色体的组型研究也逐渐应用于预测杂交成功与否、杂种能否正常生育等方面。

Results There was no hybridizing reaction with other Mycobacterium except human MTB, cow MTB, Microtus and Africa Mycobacterium.

结果 通过PCR联合探针检测结果显示：该探针除了与人型、牛型、田鼠及非洲分枝杆菌有特异杂交信号外，与其他的分枝杆菌没有杂交反应。

The results showed that there was hybridization signal on metaphase chromosome and interphase nucleus of human,but no signal on metaphase chromosome and interphase nucleus of Microtus mandarinus.According to the results,we discussed the homologue between pY3.4 in Y chromosome of humanbeing and DNA of Microtus mandarinus and FISH result of Microtus mandarinus.

结果显示，人的中期染色体上和间期细胞核中发现了杂交信号，棕色田鼠的未发现杂交信号，由此讨论了棕色田鼠DNA与人Y染色体pY3.4的同源性和棕色田鼠的FISH结果，以便进一步研究棕色田鼠Y染色体。

The result indicates that there are one dominant and one recessive complementary gene that are effective against the Indian race 2E16. However, the monosomic analysis results indicated there was one resistant gene to the Indian race 2E16 and the gene was located on chromosome 3B. The current study shows that it is different from the known genes.

采用常规杂交分析方法，对铭贤169与阿夫杂交的F_1、F_2、BC_1代及其亲本进行抗性鉴定和统计分析，结果表明，阿夫对2E16菌系的抗性至少由1对显性抗条锈基因控制；通过单体分析将阿夫抗2E16菌系的1对显性基因定位在3B染色体上，等位性分析表明该基因不同于目前的已知基因。

In this experiment, the parent strains of Pleurotus ostreatus were 9400 and 803 .143 new crossing progenies strains were abtained by monospore cross breeding, and those strains were used to attain Pleurotus ostreatus strains with properties of good quality by a series of selecting experiments.

本试验以平菇9400和平菇803为亲本，通过单孢配对杂交，获得143个杂交子代菌株，并对其进行一系列的筛选试验，旨在获得平菇优良新菌株。

Hybridization of cDNA probe and gene chip was carried out, gene chip was scanned with Scan Array3000, and results were analyzed with ImaGene 3. 0. Result: 1 Toluidine blue staining of semithin section showed: compared with control group, the boundary of tunica intima, tunica media and tunica adventitia was not distinct, tunica intima and internal elastic membrane was thickened and multilaminar.

将标记了荧光素的cDNA与细胞周期相关基因表达谱芯片杂交，扫描并分析杂交结果。cy5/cy3 ratio值在0.5～2.O之外且一对Double基因表达趋势一致的基因为表达有差异基因，ratio值＞2.O表明DM组该基因上调，ratio值＜0.5表明DM组该基因下调。

Li has also introduced chromosome engineering to the breeding of wheat strains with a "nullisomic backcross method", which has reduced the duration of wheat breeding through distant hybridization to 3.5 years, whereas the previous breeding of "Xiaoyan" lasted 20 years.

李振声还采用了缺对染色体回交的方法将染色体工程引入到了小麦强度的培育方面。通过这种方法可以将远缘杂交的时间减少到三年半。采用之前的方法，笑颜6号的杂交过程需要20年的时间。

She gently rebuff ed him, but agreed that they could be friends

她婉言拒绝了，但同意作为朋友相处。

If in the penal farm, you were sure to be criticized.

要是在劳改农场，你等着挨绳子吧！
