Genetic population structure and differentiation of Western Iranian Oxynoemacheilus argyrogramma (Heckel, 1847) using SSR markers

This study was carried out to investigate the genetic diversity and populationstructure of 90 specimens of Oxynoemacheilus argyrogramma collected fromSepidbarg, Gamasiab and Ghaleji rivers, in the west of Iran. Analyses using threemicrosatellite loci indicated that the average number of alleles in the population was 12,which was well above the reported values for freshwater fishes. The expected (He) andobserved (Ho) heterozygosity means were 0.865 and 0.576, respectively. Almost all locishowed deviation from the Hardy-Weinberg equilibrium (HWE). The resultsdemonstrated that Oxynoemacheilus argyrogramma had desirable genetic diversity inthe investigated regions.
