标记

Simple sequence repeats,alternatively called microsatellites,are regarded as useful and efficient markers for map construction of cotton,which are abundant,locus-specific,often codominant and multiallelic.

在众多的分子标记中，SSR标记具有分布广泛、位点特异性、共显性、信息量高等优点，是构建棉花遗传连锁图谱最有优势的标记。

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。

After analyzing glutinous rice waxy gene sequence reported by previous studies, two pairs of dominant and codominant STS molecular markers based PCR were designed for distinguishing glutinous rice, according to the distinctions between glutinous rice wx gene and nonglutinous rice Wx gene. Moreover, the whole sequences of the two Wx genes of nonglutinous rice reported by others were also aligned, and another two pairs of dominant STS molecular markers were designed to discriminate Wxa from Wxb based on the special site between the two genotypes. Then, corresponding rice genotypes were identified by the established new markers.

通过对前人公布的糯性水稻蜡质基因全序列测定结果的分析，根据糯性水稻与非糯性水稻蜡质基因序列位点的差异，设计了两个基于PCR扩增反应的可特异识别糯性水稻的显性和共显性STS分子标记；同时在前人公布的非糯性水稻蜡质基因的不同类型的全序列比对分析的基础上，选取了两种基因型特定的差异位点，设计了两个基于PCR扩增反应用于特异识别这两种Wx基因的显性STS分子标记，并用新建立的标记对相应的水稻基因型进行了检测。

Finally, the rules for ellipsis of conjunctional marks in C.A.S are concluded by studying whether these conjunctional marks can be omitted in sentences.

通过分析有这些关联标记的紧缩句，考察它们能否省略关联标记的情况，最后总结出紧缩句关联标记的省略规律。

The patterns are unlabeled and, therefore, there is no explicit correspondence between cluster labels in different partitions of an ensemble. An extra complexity arises when different partitions contain different numbers of clusters, often resulting in a label correspondence problem.

一方面，聚类的模式是未标记的，由不同聚类算法得到的标记之间无明显的联系；另一方面，各种划分可能含有不同的聚类个数，这就涉及到标记对应问题。
