| 摘 要： | 在红锂、镜锂和野锂中进行线粒体１６rRNA和Ｃytb基因片段的序列测定。结果发现，３个鲤品种在多达８５９个碱基长度上无变异，但是与已报道的鲤全序列中的同源序列则有约１．５％的趋异。这个结果提示３个鲤品种可能在起源中是独立的一支。并且分化极低。

| Abstract: | Mitochondrial DNA sequence analysis was carried out in 3 strains of Chinese carp ( Cyprinus carpio L. var.), i.e.red carp, mirror carp and wild carp and compared with reference carp strain of unknown origin. There were no base substitutions among 3 strains at up to 859 base pairs, however, comparison between these sequences and homologous sequence of the reference strain showed about 0.19% and 1.46% divergence at 16S rRNA and Cytochrome b sequence, respectively. These results indicate that the genetic divergence among red carp, mirror carp and wild carp is exceptionally low, and they are probably an independent branch in the evolution of carp. |
