Seven primers were screened out of 20 primers with 41 sites deprived, The results indicated that 31 bands were polymorphic sites and the frequency was 76%.The maximum genetic similarity coefficients among the 15 tigers were 0.526 3 and 0.090 9,respectively. The average genetic similarity coefficient of the population was 0.327 1.展开更多
