染色体

Thomas Hunt Morgan provided evidence that genes occur on chromosomes and that adjacent genes on the same chromosome form linkage groups.

摩根证明不仅基因就在染色体上，而且在同一条染色体上紧挨着排列的基因构成一个连锁群，往往一道遗传。

The map comprises 68 microsatellite maker loci, covering a total length of 414.3 cM, with an average distance of 6.1 cM between adjacent markers and an average marker number of 11.3 on each chromosome.

建成的这6条染色体的图谱共包含68个SSR标记座位，总长度为414.3cM，相邻标记间的平均距离为6.1cM，平均每条染色体上的标记座位数为11.3个。

The effect of phosphoric amide herbicide amiprophose-methyl, which was used wildly in agriculture, on chromosome structure and protein composition of root meristems of wheat were studied by exposure to concentrations of 1-4 μmol/L. The results indicated that, as the concentration of APM increased the frequency of chromosomal structure variation increased.

利用农业上广泛使用的酰胺类除草剂甲基胺草磷，在1~4μmol/L浓度下，对野二燕1号小麦根尖分生组织细胞染色体结构变异及蛋白质组分变化进行了研究，结果发现，随着浓度升高，染色体结构变异率呈上升趋势。

Frequencies of multipolar division cells and bridges lagging chromosome were 0.08% and 0.434% respectively when root meristems were treated with 3-4 μmol/L APM.

在3~4μmol/L浓度下处理的根尖分生组织细胞中，多极分裂细胞的出现频率为0.08%；染色体桥、断片和滞后染色体的出现频率为0.434%。

Good chromosome preparation methods are necessary to get good spreading of chromosomes within metaphases for karyotype analysis.

染色体标本的制备是核型分析最基础的工作，要制作高质量的染色体标本，获得可靠的镜检结果，必须要有很好的制片方法。

Many childhood leukemias result from mutations called translocations, where gene pieces on chromosomes accidentally relocate and misalign. In infant leukemia, the chromosome containing the MLL gene breaks within MLL and ends up fused to a different gene.

很多儿童白血病是由一种被称为易位的基因突变（染色体上基因片断突然移位重排）引起的，在幼儿白血病中，含有MLL的染色体破损，然后融合到其它基因上。

The rate of abnormal karyotype among those cases with history of mutagen contact are higher than those without contact history.

有诱变剂接触史者染色体畸变率高于无诱变剂接触史者，主要累及7、8、9号染色体。

The genomic DNA of Thinopyron intermedium labelled with biotin-16-dUTP was hybridized with the chromosomal DNA of Wheat-Th. intermedium addition Line Z,(2n = 44), which had a good resistance to barley yellow dwarf vims.

以生物素（Biotin－16－dUTP）标记中间偃麦草基因组 DNA为探针，与抗黄矮病小麦－中间偃麦草染色体异附加系Z6进行原位杂交，鉴定出附加的1对中间偃麦草染色体。

The egg production of a week et al was also analyzed . 18 pairs of microsatellite primers were screened from chromosome 1 and chromosome Z, the primers were designed to allow optimal performance of the markers, in sets containing multiple microsatellites, on ABI3100 sequencers. We determined there were correlation among 13 microsatellite markers and 19 characters in 25 egg traits through least square means. At the same time, we calculated correlation among characters of egg traits in silkies.

从鸡1号染色体和Z染色体上筛选出18对微卫星标记，进行多重PCR扩增，并对引物组合的反应体系进行优化，在F1群体中检测到13个标记位点分别与25种性状中的19种性状有不同程度的相关，并进行同一标记不同基因型间的多重比较，同时还计算了产蛋性状间的表型相关。

It was preliminarily assumed that Z〓Z〓 hybrids were fertile male, and Z〓W〓 hybrids were abnormal and sterile. Negative interactions between Z chromosome from H. assulta and W chromosome from H. armigera maybe the major reasons for abnormality of hybrids.

初步判断，正交产生的子一代中，同配性别的Z〓Z〓为有生育能力的雄性子一代，异配性别的Z〓W〓为无生育能力的畸形子一代；Z〓染色体和W〓染色体的不协调可能是造成子一代生殖器官畸形的主要原因。

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！
