凤尾鸭和红胸鸭是雁形目中两个不同分类群的鸭科鸟类。我们使用基于PCR的方法来确定这两个物种的完整mtDNA，并估计系统发育树的基础上，这些和其他14个雁形目物种的完整mtDNA比对，澄清雁形目的遗传学。利用GenBank中68个典型种的线粒体基因Cyt B、ND 2和COI的多重序列比对，构建系统发育树，进一步阐明雁形目几个类群的系统发育关系。新的线粒体DNA为环状分子，长16，651 bp（Aixgalericulata）和16，639 bp（Tadornaferrugulata），含有37个典型基因，其基因顺序和排列与其它雁形目相同。比较16种雁形目鸟类mtDNA的蛋白质编码基因，起始密码子一般为ATG，终止密码子一般为TAA，TAG和T-。除了tRNASer（AGY）和tRNALeu（CUN）缺少DHU臂外，所有的tRNA都可以折叠成典型的三叶草二级结构。根据我们对完整mtDNA和组合基因数据的分析，系统发育关系表明，小羚羊和锈毛胸天牛属于同一类群，即胸天牛亚科。分子系统发育分析表明，68种雁形目鸟类可分为3个科：雁科、鸭科和雁形目。结果表明，鸭科鸟类可分为5个亚科：鸭科、胸鸭科、雁亚科、尖尾鸭科和树天鹅亚科。Oxyurinae和Dendrocygninae不应该属于雁亚科，而是代表独立的亚科。Anatinae包括来自Mergini，Somaterini，Anatini和Aythyini部落的物种。雁亚科包括来自雁族和天鹅族的物种。
Aix galericulata and Tadorna ferruginea are two Anatidae species representing different taxonomic groups of Anseriformes. We used a PCR-based method to determine the complete mtDNAs of both species, and estimated phylogenetic trees based on the complete mtDNA alignment of these and 14 other Anseriforme species, to clarify Anseriform phylogenetics. Phylogenetic trees were also estimated using a multiple sequence alignment of three mitochondrial genes (Cyt b, ND2, and COI) from 68 typical species in GenBank, to further clarify the phylogenetic relationships of several groups among the Anseriformes. The new mtDNAs are circular molecules, 16,651 bp (Aix galericulata) and 16,639 bp (Tadorna ferruginea) in length, containing the 37 typical genes, with an identical gene order and arrangement as those of other Anseriformes. Comparing the protein-coding genes among the mtDNAs of 16 Anseriforme species, ATG is generally the start codon, TAA is the most frequent stop codon, one of three, TAA, TAG, and T-, commonly observed. All tRNAs could be folded into canonical cloverleaf secondary structures except for tRNASer (AGY) and tRNALeu (CUN), which are missing the "DHU" arm.Phylogenetic relationships demonstrate that Aix galericula and Tadorna ferruginea are in the same group, the Tadorninae lineage, based on our analyses of complete mtDNAs and combined gene data. Molecular phylogenetic analysis suggests the 68 species of Anseriform birds be divided into three families: Anhimidae, Anatidae, and Anseranatidae. The results suggest Anatidae birds be divided into five subfamilies: Anatinae, Tadorninae, Anserinae, Oxyurinae, and Dendrocygninae. Oxyurinae and Dendrocygninae should not belong to Anserinae, but rather represent independent subfamilies. The Anatinae includes species from the tribes Mergini, Somaterini, Anatini, and Aythyini. The Anserinae includes species from the tribes Anserini and Cygnini.
