基因型

Except for the Ningxia Tan sheep and Suffolk , all breeds were in accordance with the Hardy-Weinberg equilibrium.

经χ2检验后，除滩羊和萨福克羊外，其他群体的基因频率和基因型频率均处于Hardy-Weinberg平衡状态。

Quantitative fluorescent PCR was used to detect triallellic peaks or trisomic diallelic peaks to diagnosis DS depended on 1 to 4 STR loci.

国外近几年来采用荧光PCR对1～4个STR位点基因型进行分析，根据3条带或2：1的2条带图谱进行基因诊断。

Suspects of DS and 26 cases of fetal amniocytes come from pregnant woman with high risk of DS were undertook to analysis 10 STR loci simultaneously by PAGE and silver staining or automated fluorescent laser activated detector sequencer (ABI310). 6 suspects of DS were determined as DS by trisomic triallelic with a ratio of 1: 1: 1 and the other STR loci show nonnal diallelic pattern with a ratio of 1: 1 or homozygous with two alleles of the same size. The other one suspect determined as DS by 7 STR marker showing trisomic diallelic band or peak.

将10个STR位点的PCR产物用聚丙烯铣胺凝胶电泳和银染法或基因片段扫描法进行检测，结果从23例可疑患者中发现7例DS患者，其中6例均出现三条带图谱，1例虽未发现3条带图谱，但除纯合子外其余位点均表现为双倍剂量（2：1）的2条带图谱。26例胎儿羊水细胞STR基因型均表现为正常2条带图谱（1：1），表明为非DS胎儿。

Trisomic triallelic pattem is a"Gold standard"for diagnosis of DS and trisomic diallelic pattern with a ratio of 2: l also is a powerful indicator for DS.

故在21号染色体上DS关键区内选择10个STR位点（D21S11、D21S1432、D21S1413、D21S1414、D21S1446、D21S1437、D21S2039、D21S1270、D21S1411、D21S1412），根据STR基因型的表现，可进行DS的基因诊断。

Here was no significant difference in allelic frequencies of TAP1, TAP2 gene between patients and normal controls.

AP1和TAP2各等位基因基因型频率在变应性鼻炎组和正常人组间差异无显著性(P.05)。

There was no significant difference in the allelic frequency

EH组与对照组 SNP位点基因型分布和等位基因频率比较差异

No significant differences in AGT M235T genotypes and allelic frequencies among three groups.

三组间基因型分布与等位基因频率相比均无显著性差异。

Results: Three genotypes were successfully identified and expression of βB2 crystallin protein was not detected in gene knockout mice.

结果：PCR成功检测出3种基因型；纯合子基因敲除的小鼠未检测到βB2晶体蛋白的表达。

The unconditional and conditional analyses of genetic models and the corresponding statistic methods, including endospermic, cytoplasmic, and maternal plant genetic systems, were used to analyze the genetic relationships between protein content and the appearance quality traits of indica rice (Oryza sativa L.).

应用包括胚乳、细胞质和母体植株基因的遗传主效应以及基因型×环境互作效应的数量性状遗传模型及非条件和条件分析方法，研究了籼稻稻米蛋白质含量与外观品质性状间的遗传相关性，进一步揭示了籼稻糙米重、稻米直链淀粉含量对稻米蛋白质含量与外观品质性状间遗传相关性的影响。

In a large, randomly mating population that is free of disturbing forces, allele and genotypic frequencies do not change and are related in a simple way.

在一个大的，随机交配的人口是免费的令人不安的力量，等位基因与基因型频率不改变，并在有关的一个简单的方法。
