Nоrmаl develоpment оf the heаrt аtria requires left-right differentiation during embryonic development. Microarray analysis identified 77 genes with preferential expression in one of the two atria, one of the genes identified was Pitx2c. The differential expression of Pitx2c was confirmed by RT-qPCR. The amplification curve furthest to the left is of Pitx2c in the left atrium, the middle curve represents the amplification of Pitx2c in the right atrium, and the furthest curve to the right represent the represents the no template control (not relevant for this question). Based only on the data shown, which of the following statements best describes the analysis of these data?
