摘要
本试验利用ApaⅠ、BamHⅠ、BclⅠ、BglⅠ、BglⅡ、ClaⅠ、DraⅠ、EcoRⅠ、EcoRⅤ、HaeⅡ、HindⅢ、KpnⅠ、PstⅠ、PvuⅡ、SacⅠ、SalⅠ、SmaⅠ和XhoⅠ计18种限制性内切酶,研究了来自欧洲、非洲及国内的5个山羊品种共计33只个体的mtDNA,共检测出27种限制性态型,可归结为8种单倍型。结果表明,国内2个山羊品种的基本单倍型为BamHⅠ-A、BclⅠ-B、ClaⅠ-A、EcoRⅠ-A、EcoRⅤ-A、HaeⅡ-A、HindⅢ-C和PvuⅡ-A,以及为BamHⅠ-A、BclⅠ-A、ClaⅠ-A、EcoRⅠ-A、EcoRⅤ-A、HaeⅡ-A、HindⅢ-C和PvuⅡ-A,而欧洲及非洲3个山羊品种基本的单倍型为BamHⅠ-B、BclⅠ-A、ClaⅠ-A、EcoRⅠ-A、EcoRⅤ-A、HaeⅡ-A、HindⅢ-B和PvuⅡ-A,这一结果提示本研究几个受试山羊品种可能有两种不同的母系来源;同时,各品种的分子聚类图也表明国内2个山羊品种间具有较近的亲缘关系,而欧洲品种和非洲3个品种间的亲缘关系较近,这一结果也支持上述几个受试山羊品种可能有不同野生祖先的结论,同时也验证了欧洲?
Eighteen restriction endonucleases, ApaⅠ, BamHⅠ, BclⅠ, BglⅠ, BglⅡ, ClaⅠ, DraⅠ, EcoRⅠ, EcoRⅤ, HaeⅡ, HindⅢ, KpnⅠ, PstⅠ, PvuⅡ, SacⅠ, SalⅠ, SmaⅠand XhoⅠwere used to investigate the mitochondrial DNA polymorphism of different goat breeds from Europe, Africa and China Among the 33 individuals of 5 goat breeds analyzed in this paper, 27 restriction morphs were detected which could be sorted into 8 haplotypes The results indicated that the main haplotype of internal goat breeds was Ⅰ and Ⅲ, but Ⅳ for goat breeds of Europe and Africa It was pointed out that the goat breeds analyzed might originate from two different maternal side Meanwhile, the molecular dendrogram of different populations showed that the internal goat breeds had the close relationship, so did the European and African goat breeds It was also verified that the Aferican goat breed, Nubian goat was once introduced into the European goat breed, Sanne goat
