An RFLP marker shows sequence polymorphism in two ecotypes (X and Y) of a plant. In ecotype X, the marker contains one GAATTC site in its sequence, whereas in Y it has the sequence GAAATC at the same site. The rest of the sequence is identical in both ecotypes. In a genotyping experiment, the marker was PCR amplified from four different seedlings (P, Q, R, S), completely digested with EcoRI and the products were analyzed by electrophoresis. The diagram below shows the band patterns obtained. Based on the information provided, which of the following statements is correct?
