The results were the basic information to further study SNPs of MC1R gene associated with plumage color on mule duck. By using the program of Blast on GenBank, the results indicated that duck had homology with 98.4% homology with branta bernicla at nucleotide level of MC1R gene, and 92.8％～98.2% homology with other birds.

为进一步研究半番鸭羽色MC1R基因单核苷酸多态性奠定了基础；通过BLAST进行相似性搜索，结果表明，鸭与黑雁MC1R基因的核苷酸序列同源性最高为98.4％，与其他家禽的同源性也保持在92.8％～98.2%之间。

而山西平遥产山药D= 0.004 76与山西太谷产山药D= 0.004 27基本没有差异，它们和河北安国产山药D= 0.004 36共同与怀山药有较大的同源性，通过ITS序列分析，这几种不同产地的山药之间碱基仅相差几个，提示它们具有同源性；野生山药与种植山药碱基数目相差较大，说明种植山药在驯化过程中产生了变移，使物种更进化。

It is expected that hyg would be integrated stablely into the chromosome along with insert while spc/str would be lost during the second cross-over. Gene replacement through these two flanking sequences will result in the susceptibility of the transformants to phage φHAU3, which provides an enrichment for desired transformants by counterselection.

预期在携带有大插入片段的基因置换YAC分子进入野生型变铅青链霉菌后，YAC分子将通过1.4kb或1.0kb片段与染色体发生同源单交换，继而发生同源双交换，hyg连同大插入片段一起稳定地整合到染色体上，而spc／str丢失，从而导致菌株Hyg〓Str〓的表型。

It is suggested that the dioritic enclaves and their host granite were derived from the same parental magma that resulted from partial melting of the Neoprot-erozoic depleted-mantle-sourced juvenile crust.
