PCR results of using the species-specific dominant marker set on proportionally mixed DNA of P. ginseng and P. quinquefolius. Gel electrophoresis of PCR products amplified using Pg-specific primers (A) and Pq-specific primers (B) for proportionally mixed DNA of P. ginseng and P. quinquefolius. The same concentrations of both DNAs were mixed in 100:1 ∼ 1:100 ratios and the same amount of mixed DNA was used for PCR. The mixing ratio is denoted on each lane. M indicates 100 bp ladder.
