  1. N is sample size, LL represents wild type, LS represents heterozygote mutation, SS represents homozygote mutation, and Frequency is the mutation allele frequency (%). N/A means not applicable, and symbol ‘-‘stands for not done. χ 2 and P-value are the results of Hardy-Weinberg equilibrium test
