Maternal Origin of Turkish and Iranian Native Chickens Inferred from Mitochondrial DNA D-loop Sequences
Iranian Native Chicken Breeds mtDNA D-loop Haplogroup Maternal Origin
2016/11/10
To assess genetic diversity and maternal origin of Turkish and Iranian native chicken breeds, we analyzed the mtDNA D-loop sequences of 222 chickens from 2 Turkish (Denizli and Gerze) and 7 Iranian (W...
4对微卫星DNA标记在3个绵羊品种中多态性的研究
微卫星 杂合度 多态信息含量 有效等位基因
2009/5/5
选用无角道塞特、萨福克与中国美利奴肉羊品种群体, 耳组织提取基因组DNA, 用4 对微卫星引物进行PCR 扩增, 通过电泳分型、
凝胶成像系统分析各位点等位基因及全部个体的标记基因型, 计算基因频率、多态信息含量( PIC) 和杂合度等, 从分子水平上分析4 个位的遗传多态性。结果表明,CSSM18 ,OB2 ,MCM38 ,MCMA26 这4 个位点的等位基因数分别为14 、15 、13 、1...
应用DNA多态性进行山羊杂种优势预测的研究
山羊 杂种优势 RAPD
2008/9/10
该项目通过对本地山羊和波尔山羊的RAPD标记多态性研究，发现四个品种的遗传多样性比较丰富。群体遗传变异分析表明,吕梁黑山羊种内变异系数最小，阳城白山羊群内变异程度最大。四个品种间的遗传距离介于0.1827～0.3606。三个地方品种中，波尔山羊与吕梁黑山羊遗传距离最大，并且吕梁黑山羊的种内遗传变异最小。在三个地方山羊品种中，波尔山羊与吕梁黑山羊进行杂交，预计能产生较高的杂种优势。首次对山西地方山羊...
Implications for the use of horse hair roots as a DNA source for microsatellite typing
hair follicles short tandem repeats multiplex PCR
2015/6/1
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 ...
Mitochondrial DNA Polymorphism, Maternal Lineage and Correlations with Postnatal Growth of Japanese Black Beef Cattle to Yearling Age
Mitochondrial DNA Maternal Lineage Japanese Black Cattle Postnatal Growth Correlations
2016/4/18
Mitochondrial DNA haplotypes from the displacement-loop (D-loop) region (436 bp) were genotyped and sequenced in Japanese Black beef cattle raised in the same herd. Correlation coefficients between mi...
