TABLE 2

Variables of the model

VariableDescription
y, y*Actual and equilibrium prevalence of the male-killing bacteria (i.e., fraction of infected females among all females in the population)
u0, uMKFixation probability of newly arisen mutations in uninfected and male-killer-infected populations, respectively
Embedded Image, Embedded ImageExpected times until fixation of new mutations, provided fixation occurs
Embedded Image, Embedded ImageExpected times until either fixation or extinction of new mutations
FMK, HMKExpected homozygosity and heterozygosity in a male-killer-infected population
  • Note that y is used as a parameter in the first part of our model (when transmission is perfect), but is a variable in the second part (when transmission is imperfect).
