The Persian Gulf is one of the most important habitats of Pinctada radiata. The genetic information of this valuable species has largely remained unknown in the Persian Gulf. At the present study, 30 specimens were collected from the Hendourabi Island from the depths 8-10 m using SCUBA. The genetic structure of the specimens was examined. The highest and lowest gene diversity were 0.816 and 0.768, belonged to the loci M052 and M059, respectively. The highest and lowest inbreeding were found in loci M068 and M059, respectively. Number of allele and heterozygosity of the Hendourabi population were similar to other studies on other regions. Comparing the Hendourabi inbreeding with those of the other parts of the world showed that the Hendourabi inbreeding is higher than those reported for the other regions. Due to local extinction, the wide distribution of this species has reduced to smaller population nowadays. Occurrence of local extinction plus reduction of population size has decreased the genetic diversity and increased inbreeding of P. radiata populations.
