Figure 4

The probability of dying of the disease over a lifetime () at the ESS for male specific, female specific and non-sex-specific exploitation strategies as a function of the rate of vertical transmission, α Parameters=1/80 σf=σm=0; ϕ=0.5, ; ; and . For these parameters the probability of dying of the disease for males, under male specific virulence will go to an ESS value of 6%.
