杂交

Neither is the outcross of another breed.

他们的父母都没有和别的品种杂交。

Six pairs of oligonucleotide primers were designed to amplify and sequence scarlet gene of mutant stbr flies which were obtained by outcross between Bar and wild type flies.

设计了6对引物对本实验室由棒眼果蝇Bar与野生型果蝇杂交所产生的亮红眼突变型果蝇stbr的scarlet基因进行了测序，结果在scarlet基因的第4外显子检测到了一个7.5kb的插入，进一步的测序证实此7.5kb插入为逆转座子412元件。

Choose vigorous and fertile strains for out-crossing. Since inbreeding is part of the strategy for setting a new strain and inbreeding often leads to reduced fertility and vigor, the fertility and vigor of the outcross strain is important.

必须选择具有活力及多产能力的鱼种来做异种杂交所需的鱼种，因为自交也是建立创造新品系鱼种的重要改鱼步骤之一，而且自交过程通常会导致鱼只生产能力及活力的降低。

I wanted to find a way to break the cycle and began to look at experimenting with outcrossing to a new bloodline to give our domestic gene pool a chance to refresh itself.

我想要找一种打破这种循环的方法，我开始着眼于通过异型杂交而产生一种新的血统的实验，从而给我们这个大家庭的基因库一次更新它们自己的机会。

Although outcrossing is possible, most isolates are self-fertile.

虽然异型杂交可能发生，大多数菌株自交能孕。

However, outcrossing may be abandoned in favor of parthogenesis or selfing (which retain the advantage of meiotic recombinational repair) under conditions in which the costs of mating are very high.

然而，在交配代价很高的条件下，异型杂交可能被摒弃，从而有利于孤雌生殖或自交（它们保留了减数分裂重组修复的好处）。

Methods: To establish the rat model of spleen-deficiency by the methods of purgation with bitter and cold nature dyugs, omproper diet and overstrain. Immunohistochemistr and in situ hybridization were used to tetect and C-fos and C-JUNmRNA expression in the hypothalamus ventral kernel, the hippocampi CA1 area and forehead cortex.

采用苦降泻下、饮食失节加劳倦过度法建立脾虚大鼠模型，免疫组化法、原位杂交法检测下丘脑腹侧核、海马CA1区、前额叶皮层C-fos水平与C-JUNmRNA表达变化及归脾汤的治疗作用。

The experiment showed that ovule culture in overcoming cross-incompati-bility between radish and Chinese cab-bage is of significance.

试验证明胚珠培养在克服萝卜和大白菜属间杂交不亲和性方面具有一定意义。

Hybrid garden flower derived from Chrysanthemum maximum and Chrysanthemum lacustre having large white flower heads resembling oxeye daisies; often placed in the genus Chrysanthemum .

开有大白花的陆生大滨菊和湖生大滨菊的杂交园林培育品种；经常属于滨菊属植物。

Pachytene FISH results showed that most of chromosome ends possess the telomere tandem repeats,but the signals were not the same on different chromosomes in intensity.

粗线期染色体荧光原位杂交结果表明，大多数染色体的末端都有端粒串联重复，但信号的强度在不同染色体上是不同的。

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！
