Figure 1. The result of restriction enzyme digestion for rs17567. The PCR products containing rs17576 were digested by restriction enzyme Bsob1. Fragment with the G allele in site rs17576 could be cut into two periods. Lane M stands for the lane of the Marker of 100 bp to 600 bp with intervals of 100 bp ladder; Lane 1 stands for genotype A/A (222 bp); Lane 2 stands for genotype A/G (222 bp, 172 bp, and 50bp); Lane 3 stands for genotype G/G (172 bp and 50 bp).
