采用限制性片段长度多态性（RFLP）分析方法，对东北纹马林（Tetrapturus audax）的线粒体DNA（mtDNA）进行了分析。复合基因型，代表来自11种限制性内切酶的信息，分别来自墨西哥、厄瓜多尔、澳大利亚和夏威夷的约40条条纹马林鱼样本。所有样本的基因型变异相对较高：合并的核子多样性为0.82（样本范围0.69-0.84），合并的核苷酸序列多样性为0.30%（样本范围0.20-0.32%）。样本间校正的平均核苷酸序列差异值较低（0.01- 0.06%，平均0.03%）。尽管样本间差异较小，但在样本间复合mtDNA基因型的分布中观察到了显著的异质性。每个位置的特点是存在独特的基因型在升高的频率。从同一地点相隔一年采集的样本显示了时间上的...
Restriction fragment length polymorphism (RFLP) analysis of mitochondrial DNA (mtDNA) was used to determine the magnitude of intraspecific genetic differentiation among samples of striped marlin (Tetrapturus audax). Composite genotypes, representing information from 11 restriction endonucleases, were generated for samples of approximately 40 striped marlin each from Mexico, Ecuador, Australia, and Hawaii. Genotypic variation was relatively high in all samples: the pooled nucleon diversity was 0.82 (sample range 0.69–0.84), and the pooled nucleotide sequence diversity was 0.30% (sample range 0.20–0.32%). Values of corrected mean nucleotide sequence divergence between samples were low (0.01–0.06%, mean 0.03%). Despite low intersample divergences, significant heterogeneity was observed in the distribution of composite mtDNA genotypes among samples. Each location was characterized by the presence of unique genotypes at elevated frequencies. Samples taken from the same location 1 yr apart demonstrated temporal...
