后代

We are always do something for posterity , but I will fain see posterity do something for us.

我们经常在为后代做些事情，但我真想看看后代又为我们做些什么。

Now we are seeing the pretty rare Lion-tiger animal who came from Korea, the generation of a female lion and male tiger. They can copulate because they belong to felid, but the child of them cannot raise anymore and has no biology value. There are only 10 lion-tigers in the world, and the surviving ratio is just 3‰.

现在我们看到的是极其罕见的狮虎兽，它产自韩国，是由雄性狮子和雌性虎交配后所产的后代，因同属猫科动物所以能达到交配，它同马和骡子杂交的后代骡子一样，并不具有下一代繁育的能力，并没有生物学价值，全世界狮虎兽只有10余只，成活率是千分之三左右。

The low-P tolerance genetics of a set of 'Hexi41×Dabaidao' and RILs planted respectively in low phosphorous ferruginous acid red soil and high phosphorous soil were studied to investigate the expression of low phosphorus tolerance characteristics of hybrids under low-P stress, which provided the theory basis for the orderly improvement of rice germplasms with phosphorus efficiency.

以严重缺乏有效磷的酸性红壤开展合系41×大白稻强耐低磷杂种后代及重组近交系的遗传特性研究，以期明确低磷胁迫下杂种后代的耐低磷特性的表达，为磷高效水稻种质资源的定向改良提供理论依据。

Moreover, most of these toxicities caused by high-concentration chromium exposure could be transferred from exposed animals to their progeny.

而且，大部分高浓度Cr暴露导致的缺陷可以从暴露当代传递到后代，使后代仍然呈现出严重的表型与行为缺陷。

By adopting DNA fingerprints analysis and polyacrylamide gel electrophoresis simultaneously,the author made an genetical study on analytical evaluation of kindred relationship and contents of serum protein and esterase of a female hinny and her offspring bred after her mating with a masculine ass.

采用DNA指纹分析和聚丙烯酰胺凝胶电泳法，对一例与公驴交配生育了后代的母|JUE||TI|后代进行了亲缘鉴定和血清蛋白、酯酶遗传的分析。

T〓 plants were analysed and transmission of transgenes to the T〓 generation in a Mendelian fashion was verified.

转基因植株后代的遗传分析表明，外源基因在后代中呈孟德尔遗传分离。

For nonsocial animals that spawn independent young, extended lifespan is associated with good nutrition and the absence of disease and predators.

有一些非社会性的动物，它们需要生育大量的后代，但是这些后代并不需要雌性动物进行抚养，那么这些雌性动物的生育后期的时间，很大程度上需要依赖良好的营养，并且没有疾病和天敌的干扰。

If our country and France, as we hope, may go on in the enlargement and advancement of a glorious civilization, we may feel sure that if our descendants shall overtop us in wealth, in strength, in art, and equal us in love of liberty, they will not say that this was not a worthy triumph for the age in which we live, and if, unhappily, malign influences shall degrade our ivilization and our fame, and travellers and dwellers here shall find their power has waned, and their love of liberty declined, if they shall have become a poverty-stricken and debased people, what will they think of this remaining monument of a past and lost age, but that it was a creation of the godsand that no men ever lived.

如果我国和法国都像我们所希望的那样，在一个光辉灿烂的文明世界的壮大与发展中不断进步，我们就可以确信：如果我们的后代在财富、实力和艺术上超过我们，并且像我们一样热爱自由，那么他们就绝不会说这个胜利配不上我们所生活的时代；但是，如果邪恶势力不幸玷污了我们的文明和声誉，我们的后代的力量衰竭了，对自由的热爱程度下降了。如果他们已经成为一个贫困交加的、没落的民族，那么他们会如何看待一个过去的、已失落的时代留下的这座纪念碑呢！他们也许只会认为，那是众神创造的一个杰作，而从来没有人在那个时代生活过。

The fact that the pink plants were predominant among the population of RP1 cross progeny hints that the pink had the strong descendiblity, Whereas another fact that the plants with the color of another parent were predominant among the population of R01 cross progeny indicates that the nacarat/saffron plant had the low descendiblity. The above results suggest that it is better to choose the pink plants with the target color flower of breeding as a parents when arranging the cross combination. Many novel flowers with singular value of view and admire can be bred by the different cross combination since the wide segregation chromatogram is not confined to the parents'.

以RPl及R01作母本或父本，分别与不同花色杂交，F1代发生了明显的花色分离，RP1的杂交后代均以粉色占优势，表明粉色的遗传力较强，R01的杂交后代均以其它亲本占优势，表明桔黄/桔红的遗传力较弱，因此在选配组合时，最好选择具有育种目标的粉色个体作为亲本；另外由于分离谱较广，且分离的色谱范围并不完全限于双亲之间，可根据不同的杂交配组，培育出具极高观赏价值的稀有花色。

In fact, sex is invariably associated with organisms that produce a few large offspring, whereas organisms producing small offspring frequently engage in parthenogenesis .

事实上，性往往与产生少许大个的后代的生物体相关联，而产生小的后代的生物体经常进行孤雌生殖。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down

屈膝跪下。。。下跪祈祷
