Figure 1. Representative gel images of OPN1LW, OPN1MW, RHO, and OPN1SW PCR products. The first gel image represents the PCR products of OPN1LW and OPN1MW from two subjects. The size of both PCR products is 4,045 bp. M = DNA ladder. The DNA ladder positions are identified at
5, 4, 3, and 2 kb. The second gel image represents the PCR products ofRHO and OPN1SW in subjects 3 and 4. The RHO PCR product is 6,715 bp. The OPN1SW PCR product is 3,326 bp.
