Figure S1. Our evolutionary model is valid over a broad range of mating kinetics scenarios.

Figure S2. Evolution of sex ratio in finite populations.

Figure S3. Populations of random alleles have the same mean fitness as populations of natural alleles.

Figure S4. Selection coefficients on new random alleles as a function of the sex ratio evenness of the population they appear in.

Figure S5. Populations with probabilistic SD reach higher mean fitness than populations with exact SD.

Table S1. Natural populations of Tetrahymena thermophila show significant deviation from an even sex ratio.
