Fig. 7
Similarity of the natural populations to the populations simulated in the model with frequency-dependent environment. The similarity is displayed according to the value of ch, the cost of bleeding (y axis) and of infection (x axis). The similarity is color-coded according to the legend on the right. The similarity is calculated as one minus the average absolute difference between the simulated and natural genotype frequencies, hence a similarity of 1 is achieved when the genotype frequencies of the simulated populations are equal to that of the natural populations. Stars indicate an excess of homozygotes
