The original data used were 5 in 12 RFLPs of a mouse F2 population including333 individuals presented in the software MAPMAKER.Classical and successive x2 testswere used to check segregation distortions of the codominant markers. And the resultexhibited that successive x2 tests was more efficient.

以MAPMAKER中提供的老鼠F2群体中333个体12个RFLP标记中的5个连锁标记为原始数据，用传统x2检测和连续x2检测两种方法处理共显性分子标记数据，比较它们对偏分离情况分析的能力，发现连续x2检测比传统的x2检测更加准确有效。

Simple sequence repeats molecular markers are useful for a variety of applications in plant genetics and breeding because of their reproducibility, multiallelic nature, codominant inheritance, relative abundance and good genome coverage.

简单重复序列(simple sequence repeat， SSR)分子标记因其具有稳定性好、多等位基因、共显性遗传、数量丰富、基因组覆盖性好等优点，现已广泛应用于多种植物的遗传育种研究中。

As they are evenly dispersed throughout genomes, usually characterized as codominant and highly polymorphic systems amenable to genotyping by polymerase chain reaction, and generally inherited in a Mendelian fashion, microsatellites have become instrumental as genetic markers in many areas.

摘 要：微卫星标记广泛分布于原核生物和真核生物基因组中，具有密度大、多态性丰富、遵循孟德尔分离定律共显性遗传、易于PCR扩增等特点，已成为近年来最引人注目的新型DNA标记。

I want to get new colored markers.

我想要一盒新的水彩笔。

Melanoma with complete, concordant loss of these markers has not been reported.

完全、一致丢失以上表达的黑色素瘤还未见报道。

In this research, swainsonine contents of three Oxytropis species were determined by the high performance liquid chromatography coupled to mass spectrometry. The population genetic diversity was also studied and the swainsonine related molecular markers were screened by ISSR. In vitro fungi cultures from the individual plant of O. glabra were performed and microbiological morphology of the colony and the conidiophore were investigated. The 5.8S rDNA/ITS sequences of fungi amplified from total DNA in both plants and fungal endophytes were studied. These sequences were analysed and compared, and they were also compared to the 5.8S rDNA/ITS sequence of fungal enduphyte Embellisia sp. L12 from the O.lambertii, O.sericea and A.mollisimus distributed in USA.

本研究采用高效液相色谱-质谱联用法测定了三种棘豆植物的苦马豆素含量；通过ISSR分子标记技术对三种棘豆种群遗传多样性及其苦马豆素相关标记进行了研究；将小花棘豆植物单株进行体外真菌培养，研究了菌落和分生孢子的微生物形态学特性，从植物总DNA和相同植株培养的真菌总DNA扩增真菌的5.8SrDNA/ITS区，进行了DNA序列分析与排序；联系单株小花棘豆的苦马豆素含量测定和内生真菌ITS序列分析结果，与从美国分布的二种棘豆(O.lambertii、O.sericea)和一种黄芪(A.mollisimus)中分离的内生真菌埃里砖格孢属Embellisia sp.L12株得到的结果进行了比较。

Each compensation pin is a contraposition marker in a crossing or T shape, and the contraposition markers are positioned on the outside of the component hole and glued on the bendable dielectric layer.

每一补强引脚是具有一概呈十字或是T字形的对位标记，该些对位标记是位于该元件孔之外而贴附于该可挠性介电层。

Thereby, the contraposition markers have advantages of cooperating contraposition for inner lend connecting, easy manufacturing and ensuring non-distorting for the coiling tape.

因此，该些对位标记具有在内引接合时协助对位、容易制作并确保该卷带不易扭曲变形的功效。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
