Differences in distribution of fluorescence intensity between simple SNP and hemi-SNP. The green bar represents the fluorescence intensity of fluorophore Cy3, while the red bar represents the fluorescence intensity of fluorophore Cy5. The genotypes of the polymorphic sites are shown in parentheses. (a) The distribution of fluorescence intensity for a simple SNP. The theta value could be clustered into three categories in the mixed population. (b) The distribution of fluorescence intensity for a hemi SNP. The theta value could be clustered into two and three categories in the individual population, while the theta value could be clustered into four or more categories in the mixed population.
