Refer to the figure. An amplicon for gene X is 176 base pairs (bp) in size. A variant allele x, gives the same size amplicon but has an Alwl restriction enzyme recognition site that is not present in the amplicon arising from allele X. A PCR reaction is run on a DNA sample isolated from 3 patients. The sample is digested with Alwl after the PCR is complete and products of the digestion are resolved on a 4.0% agarose gel.Assuming all appropriate controls have worked correctly, what is the interpretation of the genotype of patient #3 with regards to alleles X and x?
