Bimodal Gene Expression Patterns: Plot A shows the proportion of samples with missing values calculated for each gene. The overall distribution of the missing rate is bimodal with the majority of genes either having few (< 5%) or many (> 95%) missing values. Genes were classified as ‘constitutive’ (< 5% missing), mixed (5–95% missing), or repressed (> 95% missing). Constitutive genes are those to the left of the red dashed line. The mean value of non-zero TPMs for expressed genes also had a bimodal distribution based on the missing rate. Plot B shows the density plots of constitutive and non-constitutive genes
