In Taqman assay for detection of base substitutions (DNA Variant), probe (oligonucleotides) with fluorescent dyes at the 5' end and a quencher at 3' end are used. While the probe is intact, the proximity of the quencher reduces the fluorescence emitted by the reporter die. If the target sequences (wild type or variant) are present, the probe anneals to the target sequence downstream of one of the primers used for amplifying the DNA sequence flanking the variants. For an assay, two flanking PCR primers, two probes corresponding to the wild type and variant alleles and used, each labeled with two different reporter dyes and quencher. During the extension, the probe may be cleaved by taq polymerase  separating the reporter dye and the quencher. Three individuals were genotyped using this assay. The sample for individual I shows maximum fluorescence for the dye attached to the wildtype probe, the sample for individual II shows maximum fluorescence for the dye attached to variant probe; and the sample for individual III exhibits equal fluorescence for both the dyes. Which of the following statements is correct:
