Abstract
The aim of present study was to investigate the genetic diversity of Garra persica populations in the Beshar and Kabgiyan rivers in Kohgiluyeh and Boyer-Ahmad province by using six microsatellite loci. In this study fulfilled on 56 Garra individuals. According to the results, the Fst value was 0.024 which indicates the low genetic differentiation between the populations. The number of alleles, observed and expected heterozygosity were, 7-25, 0.000-1.000 (the average: 0.595) and 0.767-0.946 (the average: 0.855), respectively. This indicates the allelic diversity and genetic variation of investigated populations is at favorable level. Also, analysis of molecular variance showed there is low genetic variation among populations and most of the observed variation is within the populations. According to these analyses, it seems that, Garra persica has desirable genetic diversity in investigated regions.
