染色体

This provided a new technical support to studying regulation, chromosome structure and chromosome translocation identification and accurate measurement and localization of translocated chromosomes.

这为研究细胞有丝分裂的调控、染色体形态结构、易位染色体检测和易位染色体片段的精确测量与定位等提供了新的技术支撑。

The crossover operation in the traditional GA operating is that choose two chromosome cross only at random also you can cross a bit, match and cross partly, cross order and cross cycle etc.

传统GA算法中的交叉操作，是随机选取两个染色体进行单点交叉(也可以多点交叉、部分匹配交叉、顺序交叉和周期交叉等等)，但是不管是采用何种交叉操作，新的子代染色体某一基因位上的值都是由两个父代染色体中相应基因位值经过一定交叉运算(直接交换或经算术运算等)所得到的，采用这种交叉算子操作使群体经过多次迭代后群体中的个体开始出现极大的相似性，因此照此下去就会出现早期收敛现象，使得算法的收敛速度非常慢甚至只能求到问题的局部最优解。

The results show that, Pian Nui can form the structure of SC in autosomes of a few primary spermatocytes and has more synaptonemal abnormalities.

根据研究结果，作者认为牦牛与普通牛在部分常染色体和性染色体上的差异，使犏牛的同源染色体不能很好地配对形成SC ，是导致不育的主要原因之一。

Chromosomes are the genetic material that contain the code of life: Deoxyribonucleic acid, better known as DNA. Of those 46 chromosomes, 44 are grouped in a total of 22 pairs and are called autosomes , the name given to the non-sex determining chromosomes that determine other characteristics.

染色体是遗传物质中包含的代码生活：脱氧核糖核酸，更好地称为DNA的那些46染色体上， 44个分组，在共二二双被称为 autosomes ，名称考虑到非性别决定的染色体确定的其他特点。

Suppression of recombination is the prerequisite for plant sex chromosome evolution from a pair of autosomes. Recombination suppression around the locus controlling sex determination results in sex chromosome degeneration and differentiation.

重组抑制是植物性染色体由常染色体进化而来的前提条件，性别决定位点区域发生的重组抑制使早期的性染色体发生了退化和分化。

Besides these, different kinds of chromosomes were discriminated exactly by initial analyzing the bandings of Trachinotus ovatus, which made karyotype analysis much more standard.

在此基础之上，我们还对卵形鲳鲹进行了初步的带型分析，发现以染色体带纹为标记，可以更准确的识别染色体，确定同源染色体，使对卵形鲳鲹的核型分析标准化。

Its chromosome number was 42, and 21 bivalents could be observed at PMC MI. FISH analysis by using genomic DNAs from S. cereale and genomic DNAs from L.

染色体观察结果表明，山农030-1根尖染色体数目为42，花粉母细胞减数分裂中期I染色体构型为2n=21Ⅱ。

The improved technique succeeded in the preparation of chromosome specimens of blackfly salivary gland, which was convenient for the observation of chromosomes shape and chromosomes variation in the laboratory.

改进的蚋类唾腺多线染色体制备方法可获得较满意效果，便于观察染色体形态和研究染色体结构变异等。

2QTL model for total meat content, loin eye area and bone percentage had reached chromosome-wide level (P.05) and a significant improvement on the one-QTL.

在确认瘦肉量、眼肌面积和骨率1个QTL染色体水平显著情况下，用同一染色体2个QTL模型也达到了染色体显著水平，且比1个QTL模型解释更多的表型变异。

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！
