| 摘 要： | 在形态学分析的基础上,对有棘和无棘两种不同表型栉江珧(Atrina pectinata)的28S rDNA和COI基因片段进行序列分析比较.结果显示这两种表型的DNA序列差异很小,28S rDNA(1 075 bp)无差异,而COI(659 bp)碱基差异最大为1.5%,不能提供这两种表型的栉江珧划分为两个种的证据. |

| Abstract: | The ANOVA analysis was conducted to the length, height and width of shells of scaly and non-scaly phenotypes in species of Atrina pectinata. We use DNA sequence data from the nuclear 28S rDNA and mitochondrial cytochrome oxidase I (COI). The length of sequenced 28S rDNA genes is 1 075 bp, and COI's is 659 bp. There are little differences between the DNA sequences of the two types of A. pectinata. It is suggested that the two types of A. pectinata should belong to the same species. |
