嵌合现象

Pollen as the target for gene transfer is a potential plant transformation system which can avoid the problens of somaclonal variation and chimaera resulting from in vitro regeneration.

以花粉作为外源DNA的媒介，获得转基因植株是有潜力的遗传转化体系。它可避免离体培养过程中的遗传变异和转基因植株的嵌合现象。

This study uses the height function to track the free surface, and the body-fitted coordinate system is used to generate a coordinate surface coindent with the boundary contours in the physical plate.

为求解本研究的流动现象，除了以高度函数法追踪液面外，并以物体嵌合座标系统克服翼形的不规则形状，同时采用SIMPLE数值法来处理整个数值运算过程，并配合交替方向隐式A.D.I。

Chromosome mosaicism is not the only genetic difference between males and females.

染色体嵌合现象并不是男性与女性之间唯一的基因差别。

However, mosaicism of both CGG repeatlength and methylation status exists in fragile X patients.

全突变经常是嵌合性的，甲基化现象也会嵌合发生。

The positive ratio through injecting the foreign gene to the sperm reservoir is higher than to that through injecting it to the copulatory pouch.

将外源DNA注射进雄蛾贮精囊比注射到雌蛾交配囊后代有更高的阳性率，且同蛾区嵌合现象轻些。

They havedone so by showing that chimerism extends to all sorts of tissues, includingmarmoset sex cells.

她们进一步揭示了嵌合现象延伸到了各个生理组织，包括狨猴的生殖细胞。

But one possibility is that, in a species in whichfemales routinely mate with several males, chimerism evolved as a way of dupingmales into looking after offspring that are not their own.

但是有一个可能是，在某些物种的世界里，雌性动物会通常与好几个雄性动物交配，而嵌合现象就逐渐成为蒙骗雄性动物的一种方式–雄性动物就此会好好照顾那些不属于自己的子女。

This done, shetried to work out whether chimerism influenced parental care in marmosets.

在此发现之后，罗斯博士又尝试了研究嵌合现象是否会对狨猴双亲关爱有任何影响。

The results indicated that the c-terminal fragment of Arabidopsis CRY1 gene was successfully integrated into the rape genome, mainly in the form of tabling, with a few in the form of single copy. The transformed gene could be stablytransmitted in the progeny, with a transmitted line rate of 62.5%. The genetic pattern of the transformed gene in the T_2 generation was mostly non-Mendelian. The transgene was expressed in some of the transgenic plants, but kept silent, in other plants.

结果表明，转化的外源目的基因多数以嵌合形式，少数以单拷贝形式整合到转基因甘蓝型油菜的基因组中；目的基因能稳定地遗传给后代，株系间遗传传递率为62.5％；T_2代的遗传行为少数呈现孟德尔遗传，多数呈现非孟德尔遗传现象；拟南芥CRY1基因能在转基因油菜中表达，但也出现了沉默现象。

Of 9 female recipients of livers from male donors had chimerism in their allografts and extrahepatic tissues, according to in-situ hybridisation and molecular techniques 10 to 19 years posttransplantation.

肝移植后10－19 年，根据原位杂交和分子技术，9 名接受男性肝脏移植的女性受体的肝脏及肝外组织均存在嵌合现象。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
