Intra-species variations in the species of <i>B. tauricus </i> were determined using mitochondrial DNA cyt <i>b </i> squencing. The population genetic structure was revealed by analyzing the molecular variance (AMOVA). </span> <span lang="it" style="font-size:12pt;line-height:107%;font-family:’Times New Roman’, serif;" xml:lang="it">For this study, a member of the related fish group, <i>Cyprinus carpio </i> L., 1758 (DQ868874.1)(as an outgroup) and other <i>Barbus </i>species from the GENBANK database was used in comparative analyses. </span> <span lang="tr" style="font-size:12pt;line-height:107%;font-family:’Times New Roman’, serif;" xml:lang="tr"> Therefore, total sequence of 1141 bp of the cyt <i>b </i> gene region was obtained and 11 haplotypes were determined. The molecular data obtained by AMOVA revealed that there were intraspecific variations of <i>B. tauricus </i> and that 26.61% of the variation were among the populations. The F <sub>ST </sub> value estimated for all populations and loci confirms genetic heterogeneity in <i>B </i>. <i>tauricus </i> populations (F <sub>ST </sub>= 0.59310). Genetic analyses revealed that <i>B. tauricus </i> populations are geographically structured. </span> </p> <hr /> <p style="text-align:justify;"> <span lang="tr" style="font-size:12pt;line-height:107%;font-family:’Times New Roman’, serif;" xml:lang="tr"> <br /> </span> <br /> </p>}, number={1}, publisher={Ege University}
