Abstract: Objective To evaluate the genetic structure of Tiger skin population by microsatellites. Method 37 microsatellites were applied to amplify the 25 genomic DNA by PCR. Software POPGEN1. 32 was used to analyze the scanning result of PCR products. The parameters of genetic structure of Tiger skin population were obtained. Result The observed average number of alleles is 4. 702 7. The average effective average number of alleles is 2.6907. The average effective heterozygosity is 0.602 1. The average polymorphism information content ( PIC) is 0. 552 0. Conclusion Microsatellites can be used to genetic quality monitoring of Tiger skin population. The genetic background of Tigers kin population is in conformity with the characters of closed colony.
