Fig. 7From: Tracking the evolution of cancer cell populations through the mathematical lens of phenotype-structured equationsThe level of intrapopulation heterogeneity decreases as the drug concentration increases. Plot of the level of intrapopulation heterogeneity at equilibrium \(\overline {\sigma }^{2}_{c}\) as a function of the drug concentration c(·)=C for the parameter values listed in Table 1 Back to article page
