Fig. 8

Average genotype frequencies in the model with a constant environment, without mutation. The frequencies are displayed according to the cost of bleeding (y axis) and of infection (x axis). For the non-pathogenic environment all c_h values are equivalent since c_i = c_h = 0 in all cases. For the pathogenic environment, models with varying c_h values are shown. The average genotype frequencies across 100 simulations using the HWE-process without mutation, each with 10,000 generations, are displayed. The frequencies are color-coded according to the legend on the right. Stars indicate an excess of homozygotes
