Mitochondrial DNA sequence variation in 655 bpfragments of the cytochrome oxidase c subunit I gene, known as the DNA barcode, of European anchovy (Engraulis encrasicolus) was evaluated by analyzing 1529 individuals representing 16 populations from the Black Sea, through the Marmara Sea and the Aegean Sea to the Mediterranean Sea. A total of 19 (2.9%) variable sites were found among individuals, and these defined 10 genetically diverged populations with an overall mean distance of 1.2%. The highest nucleotide divergence was found between samples of eastern Mediterranean and northern Aegean (2.2%). Evolutionary history analysis among 16 populations clustered the Mediterranean Sea clades in one main branch and the other clades in another branch. Diverging pattern of the European anchovy populations correlated with geographic dispersion supports the genetic structuring through the Black Sea-Marmara Sea-Aegean Sea-Mediterranean Sea quad.
通过分析来自黑海、经马尔马拉海和爱琴海至地中海的16个种群的1529个个体，评估了欧洲鳀（Engraulis encrasicolus）细胞色素氧化酶c亚基I基因655 bp片段（即DNA条形码）中的线粒体DNA序列变异。在个体间共发现19个（2.9%）可变位点，这些位点定义了10个遗传分化种群，总体平均距离为1.2%。东地中海和北爱琴海样本之间的核苷酸差异最高（2.2%）。对16个种群的进化历史分析将地中海分支聚集在一个主要分支中，其他分支聚集在另一个分支中。欧洲鳀种群的分化模式与地理分布相关，这支持了通过黑海-马尔马拉海-爱琴海-地中海区域的遗传结构。
