Results There was no significant gene difference between adults and larvae. CO Ⅱ gene sequences could he used to identify Boettcherisca peregrina, Aldrichina grahami and Lucilia illustris but they could not distinguish Lucilia cuprina from the Lucilia sericata because of their close evolutionary distance and single nucleotide polymorphisms in aldrichina grahami and Lucilia illustris populations were found.

结果 成虫与幼虫基因差异不明显，COⅡ基因序列可以对棕尾别麻蝇、巨尾阿丽蝇和亮绿蝇进行鉴定，铜绿蝇与丝光绿蝇进化距离较近，COⅡ序列不能将他们区分开，同时还发现巨尾阿丽蝇和亮绿蝇存在种群单核苷酸多态性。

因此，恒河猴MHC多态性的研究，有助于生物科学的发展及指导以恒河猴为动物模型的各种实验。

A single nucleotide polymorphisms which can result in the change if amino acid sequence is found in a pedigree congenital monilethrix.

Acerifolia. Here, 16 primers out of 38 ISSR primers screened, were found to produce clear reproducible bands resulting in a total of 103 distinct bands, Of these 103 bands, 86 were monomorphic across all 20 of the plants tested and 17 showed polymorphisms (16.5% polymorphism).

研究结果表明：从38条ISSR引物中筛选得到16条引物可以产生明亮清晰、重复性高的条带，条带总数为103条，其中86条条带表现为一致性，在20个快繁苗中无任何差异；而剩下的17条条带表现为多态性(多态率16.5％)。

The chromatin unfolding assay showed that ,like the wild-type transactivation domain, two variants that represent benign polymorphisms did not induce chromatin unfolding or only induced subtle change. Contrary to the behaviors of the wild type and two benign variants, four cancer-predisposing mutations in the transactivation domain superactivate the chromatin unfolding. The results suggest that the chromatin unfolding assay can aid in the characterization of deleterious mutations in the C-terminal transactivation domain of BRCA1 and may provide more reliable presymptomatic risk assessment.

对这些重组质粒的染色质伸展活性检测表明，野生型pwt和两种良性多态性突变体不具有染色质伸展活性或只有极微弱的染色质伸展活性，而其他4种乳腺癌易感突变体均具有过强的染色质伸展活性，提示利用染色质伸展技术可预测BRCA1转录激活区基因型与乳腺癌发生风险的表现型的关系。

They were mainly of pretibial or pretibial/Pasini mixed type. With two-point linkage analyses, Alu I and Msp I polymorphisms were not informative for all families. Pvu II polymorphism was informative in 2 families with a combined lod score of 1.593 at .theta.

我们对其中的6个以胫前型表现的DEB家族进一步用Intrageic Puv II及Flanking Msp I，Hind III pelymorphic markers作Two point及Multi-point连锁分析，结果用两点连锁分析，只有两个家族的Puv II marker是Informative ，合起来得到Z=1.593，。theta。
