Number of tissue-specific genes. For each human tissue, we counted the number of genes differentially expressed between this tissue and all the other eight tissues. Grey bars are for the GP model and the white bars are for the Poisson model. The shaded regions represent the shared genes between the GP and Poisson models. Only genes with existing MLEs of the parameters for both the GP and the Poisson models in the two compared samples were considered.
