Figure 3. Regions of the parameter space for the evolution of non-reproductive workers for single and for double mating.
(A) For single mating, n = 1, the invasion of a recessive worker sterility allele depends on the parameters p0 and r1/2; for double mating, n = 2, it depends on the parameters p0, p1/4, and r1/4. (B) The evolutionary stability of a recessive worker sterility allele depends on the parameters p0, r1/2, and r1 for single mating, and on the parameters p1/2, r1/2, and r1 for double mating. We set r0 = 1 as baseline.
