Figure 8. Regions of the parameter space and evolution of worker sterility for a dominant sterility allele.

The evolutionary invasion of a dominant worker sterility allele depends on values of the parameters p_1/2, r_1/2, and r₁ for single mating, n = 1, and on values of the parameters p_1/2 and r_1/2 for double mating, n = 2. The figure shows four parameter regions indicating whether or not worker sterility can evolve for single or double mating. We set r₀ = 1 as baseline.
