Genetic variation within and between five Iranian sheep populations; Sanjabi (SAN), Kordi Kordistan (KKO), Kordi Khorasan (KKH), Mehraban (MEH) and Moghani (MOG) was assessed using 6 microsatellite markers (McMA2, McMA26, MAF64, OarAE64, OarCP26 and OarFCB304). There are significant deviation from Hardy-Weinberg equilibrium in all population-locus combinations except the locus McMA2 in the MOG population (p<0.005). The lowest DA genetic distance (0.234) was obtained between KKH and KKO and the highest (0.388) between SAN and MOG. D based on DA distances, neighbor-joining revealed one cluster containing KKO, KKH and SAN and another cluster with MEH and MOG. The average expected heterozygosity within populations ranged from 0.744 to 0.847 for KKH and MEH, respectively. The estimated time of divergence for two Kordi populations (KKO and KKH) was 445 years that has accordance with historical evidence. This study showed that microsatellite loci can be an useful tool for evaluating variation evolutionary relationships among local sheep populations.
