查询词典 polymorphism

The data byχ~2 were consistent with the separation ratio as 1: 2: 1 χ~2=4.028＜χ_(0.05,2~2=5.99, which further conformed that glandless character was controlled by a incomplete dominance gene, Gl_2~e. 2. SSR markers every about 5cM were selected in the chromosome 12 of our lab genetic linkage map to screen the parent plants. The markers with the polymorphism were used to amplify the DNA of 210 F_2 segregating plants selected randomly and recorded the marker genotypes. After eliminating the segregation distortion markers byχ~2 test, other SSR markers were detected by linkage analysis.

二、参照本实验室海陆种间遗传连锁图谱第12染色体上的SSR标记，平均每5cM左右选择一个标记进行亲本多态性的筛选，筛选出具有多态性的标记位点进一步扩增随机抽取的210个F_2群体单株的DNA，鉴定每个个体的标记基因型。X~2检测剔除偏分离标记后进行连锁分析，发现Gl_2~e基因位于CIR362与NAU5079之间，进一步参考图谱上位于CIR362与NAU5079之间的标记加密图谱，最终将其定位在CIR362和NAU2251b、NAU3860b、STV033之间。

Rep-PCR method was used to conduct cluster analysis to the 39 bacterial isolates. rep-PCR analysis revealed that the 39 bacterial isolates could be divided into 12 clusters at the 0.9 dissimilarity percentage level. The 39 bacterial isolates had their own specific band patterns, showing obvious genomic heterogenicity and rich genotypic polymorphism genetic diversity between each isolate.

采用rep-PCR技术对39个细菌分离株进行聚类分析，在rep-PCR图谱的相异百分数为0.9的水平上被聚类为12个类群，39个分离株各自具有独特的带型，说明各细菌分离株的基因组之间存在显著异质性，表现出丰富的基因型多态性。
