The present invention provides a genotype determination device and method for improving the accuracy of determining a genotype in a genotype determination technique using a DNA microarray. The genotype determination device according to one embodiment is provided with a representative value calculation unit, a first labeling unit, a model construction unit, and a second labeling unit. The representative value calculation unit calculates, on the basis of signal strength, the representative value of each cluster for the clusters of per-SNP specimens classified on the basis of the signal strength of a plurality of specimens in a plurality of SNPs. The first labeling unit assigns a genotype to each cluster of SNPs classified into three clusters on the basis of the representative value of each cluster. The model construction unit constructs a model indicating relationship between the genotype and the representative value of each cluster of SNPs classified into three clusters. The second labeling unit assigns a genotype to each cluster of SNPs classified into one or two clusters on the basis of the representative value and model of each cluster. |
