Lineage Selection and the Maintenance of Sex

Figure 1

Schematic representation of the models developed here for exploring the maintenance of sexual reproduction.

a: Model without competition. pS and pA are the speciation probabilities of sexual and asexual lineages, respectively, eS and eA are extinction probabilities for sexual and asexual lineages, respectively, and uS is the probability of transition from sexual to asexual states. While pS, pA, eS and eA are fixed over generations, the transition rate uS can evolve. b: Model with competition. The parameters are explained on the figure. For the two models, all simulations start with a single sexual lineage.
