【摘要】 研究了草地藏系绵羊mtDNA D-Loop区多态性,获得了草地藏系绵羊mtDNA D-Loop区全长序列信息,这一区段的DNA长度为1179～1183 bp(A型)和1106 bp(B型),其长度存在明显差异,这主要是由于该区内串联重复序列数目的不同造成的,因此草地藏系绵羊可分为A型(3个重复)和B型(4个重复)两种类型。更多还原

【Abstract】 The mtDNA D-Loop Polymorphism in Tibetan sheep was studied.The sequences of D-Loop region in Lawn Tibetan sheep were obtained and the sequence length were 1179～1183bp(type A) and 1106bp(type B).The obvious difference of the sequence length in D-Loop region there,which is mainly due to the different numbers of tandem repeated sequences in this region.Thus,Tibetan sheep can be classified into type A(3 replicates) and type B(4 repeats).更多还原
