摘要采用多重PCR的方法,以快速扩增微卫星标记和节约试剂为目标,对其反应条件进行优化后,获得了46个扩增效果理想的微卫星标记多重PCR组合,其中30个为二重PCR,16个为三重PCR。实验结果表明,这些多重PCP反应的引物浓度为0.06~0.3μmol/L, Mg2+的浓度变化范围为1.5~3.0mmol/L,采用的PCR缓冲液的倍数为1.0、1.2、1.4或1.6,每个PCR反应聚合酶的用量在0...
摘要采用13号染色体上与K88ab和K88ac受体基因连锁的2对引物(S0223和S0068),研究沙子岭猪和大约克猪的遗传差异性。结果表明,2个猪种在2个基因座均存在多态性,其基因杂合度和Shannon信息指数存在很大差异,而中外猪种的K88ab和K88ac受体基因也存在遗传差异,这2对引物可望作为K88ab和K88ac受体基因的遗传标记。Abstract: The genetic variat...
摘要 经多重PCR扩增20个微卫星标记,对凉山半细毛羊进行亲权鉴定。荧光标记检测扩增产物,并用Cervus 2.0分析。结果表明:当双亲未知时,累积排除概率为0.998666 ,在父系半同胞基础上进行母子亲权鉴定,累积排除概率为0.999994,置信度为95%,最终从8个候选父亲中找出215个后裔的父亲,又从147个候选母亲中找出它们的母亲,构建了一个混合家系系谱,为进行连锁分析、QTL定位...
摘要 五指山猪是我国著名的珍稀畜种,体型小、性成熟早、遗传稳定、近交程度高,可用于医学、药学和生物材料等方面。作者利用多重PCR和基因扫描技术对五指山猪13个家系的32个微卫星基因座进行遗传检测。统计各家系的等位基因组成,计算各家系的平均杂合度和多态信息含量(PIC);结果,各家系32基因座的平均等位基因数为13.66个,平均PIC为0.731,平均杂合度为0.559。表明海南五指山猪具有丰富的...
摘要微卫星是以1~6个碱基为基本单元的串联重复序列,由于具有共显性、多态性高和容易用PCR方法检测等特点,是非常有用的遗传标记。在小麦中,SSR标记已广泛应用于遗传图谱的构建、遗传多样性、品种及基因型鉴定、目的基因,以及QTL的标记和标记辅助选择育种。 Abstract:Microsatellites are simple,tandemly repeated one to six nucleot...
Microsatellite polymorphism and the genetic relationship were estimated using genotype information of 305 horses from 11 microsatellite loci. The breeds include the indigenous Korean breeds, Korean na...
Molecular characterization of Hallikar, the native cattle breed of Karnataka, was undertaken using 19 cattle specific, highly polymorphic microsatellite markers recommended by FAO. The genomic DNA was...
In German Holstein population a very signifi cant QTL with effects on milk yield trait (MY) was mapped on chromosome 6 and 20 to the interval BM143–ILSTS97 and AGLA29–ILSTS72, respectively. Where, thr...
Hair roots are a very attractive source of DNA for microsatellite-based parentage control of breeding animals. However, unlike blood samples, irregular DNA typing results have been observed in assays ...
The work reported here is an attempt to explore the possibility of DNA microsatellite loci transfer (cross-species amplification) to other economically important aquacultured catfish species other tha...
Genetic variation at 25 microsatellite loci, population structure, and genetic bottleneck hypothesis were examined for Ankleshwar poultry population found in Gujrat, India. The estimates of genetic va...
This study was conducted to establish an individual identification system comprising of 19 microsatellite markers located on different bovine autosomes. The markers were typed on 257 animals from five...
This study was performed for parentage verification of the Korean native horse (KNH). 103 random KNH samples (including 19 foals for parentage testing) were genotyped by using 16 microsatellite marker...
The genetic diversities and relationships of 10 Chinese indigenous pig breeds and three exotic pig breeds have been evaluated using 26 microsatellites recommended by the Food and Agriculture Organizat...
The objective of the present study was to explore associations between five microsatellites linked to FecB and FecXI genes and litter size in Small Tail Han sheep. The polymorphisms of five microsatel...
