| 摘 要： | 为了探究我国小型鹅种的系统进化,运用DNA测序技术测定了我国13个小型鹅种群体mtDNA D-loop区521 bp序列。结果显示这13个小型鹅种D-loop区的A、G、C、T含量分别为32.2%,15.0%,29.0%,23.8%。平均单倍型多样度和核苷酸多样度分别为0.2153和0.00046。13个家鹅种间变异大于种内变异,且均未出现群体扩张现象。群体聚类和系统进化树表明,伊犁鹅来源于灰雁（Anser anser）,其余12个鹅种来源于鸿雁（Ansercygnoides）

| Abstract: | To study the systematic evolution of Chinese light-body type goose,the 521bp control region(D-loop) of mitochondrial DNA from13 light-body type goose breeds were sequenced.The results showed that in the D-loop region of the 13 goose breeds,the content of A,G,C and T nucleotides was 32.2%,15.0%,29.0% and 23.8%,respectively.The average haplotype diversity(Hd) and nucleotide diversity(Pi) of domestic ducks were 02153 and 0.00046,respectively.The 13 goose breeds had bigger nucleotide variance value among popula... |
