    Abstract: A gene polymorphism analysis device for determining the allele mating type of a gene polymorphism on the basis of the first fluorescence intensity change over time and the second fluorescence intensity change over time measured on the first allele and second allele that constitute a gene polymorphism of a target DNA. The determination of the allele mating type of the gene polymorphism is performed on samples arranged in M rows and N columns, and the determination results and graphs are displayed on a display device. The graphs show the first fluorescence intensity change over time and the second fluorescence intensity change over time of each sample. The determination results and the graphs are arranged in M rows and N columns so as to correspond to the layout including M rows and N columns of the samples.
