Fig. 6.

Frequency distribution of the different types in equilibrium after invasion of a CI+MK double infection into an uninfected population. Frequency distributions are shown in dependence of the relative fecundity of females infected with the male-killer, F _MK, for F _CI < 1 (a) and F _CI > 1 (b). Parameters take the values F _CI = 0.96, l _CI = 0.9 (a), F _CI = 1.02, l _CI = 0.1 (b), t _CI = 0.99, t _MK = 0.95, β = 0.2, and v = 0.1
