| 摘 要： | 为了探究我国灰鹅品种的遗传多样性和系统进化,运用DNA测序技术测定了我国13个灰鹅品种mtDNAD-loop区521bp序列。结果表明:这13个灰鹅品种521bpD-loop区序列的T、C、A和G碱基含量分别为23.8%、29.0%、32.3%和15.0%;平均单倍型多样度和核苷酸多样度分别为0.19245和0.00036;13个灰鹅种间变异大于种内变异,且均未出现群体扩张现象;共享单倍型和系统进化树分析表明,伊犁鹅起源于灰雁(Anser anser),其余12个灰鹅品种起源于鸿雁(A.cygnoides)。

| Abstract: | In order to reveal the genetic diversity and systematic evolution of Chinese greylag goose breeds,the 521 bp control region(D-loop)of mitochondrial DNA from 13 greylag goose breeds were sequenced.In the D-loop,the contents of T,C,A,and G nucleotides occupied 23.8%,29.0%,32.3%,and 15.0%,and the average haplotype diversity(Hd)and nucleotide diversity(Pi)were 0.19245 and 0.00036,respectively.The nucleotide variance value among the populations was bigger than that within the populations,and no population expans... |
