  1. *The 15 individuals were randomly selected from all samples to avoid bias from sample size in calculating genetic diversity
  2. Different letters in the same column indicate significant differences at P < 0.05
  3. A number of alleles, Ae effective number of alleles, Ho observed heterozygosity, He expected heterozygosity, FIS fixation index
