## Competition between populations with different rates of recombination.

In (A), (B) and (C) we plot the changes in the ratio of the higher rate recombining population #1, relative to the lower rate recombining population, #2, 1∶2. Runs initiated with 10 randomly chosen clones with identical starting populations for the 1 and 2 populations. In all runs the runs depicted the total population size *N _{T} = 2×10^{8}*, μ = 10

^{−8},

*χ*,

_{1}= 5×10^{15}*χ*

_{2}= 0, c = 0.50, e = 1.0. (A) Initially equal densities of 1 and 2 and no fitness cost associated with recombination. (B) Initial equal frequencies of #1 and #2M and a 1% fitness cost for the recombining population 1. (C) The recombining population is initially rare and there is no fitness cost associated with recombination. (D) Ratio of non-recombining to recombining 2∶1, the non-recombining population is initially rare and there is a 2% fitness cost for the recombining population.
