Fitness consequences of biased sex ratios. Relative fitness compared to (a) an unadjusted sex ratio of 0.5 and to (b) a constant ratio of 3/14 of a focal foundress when she lays an unadjusted sex ratio of 0.5 (open squares; UA females), a constant, but adjusted sex ratio of 3/14 (open triangles; IA females), and an adjustment for foundress number as predicted in Eq. (2) and 0.1 for single foundresses (solid circles; E2 females). Lines connect relative fitnesses of each kind of focal female. c The relative fitness of a range of sex ratios compared to the optimal ratio of 3/14 in a two-foundress patch where the other female lay the optimal ratio of 3/14. Colours indicate relative fitness brackets: black is w > 0.995, red is 0.995 > w ≥ 0.99, orange is 0.99 > w ≥ 0.98, yellow 0.98 > w ≥ 0.96, green is 0.96 > w ≥ 0.92, blue is 0.92 > w ≥ 0.84, violet is 0.84 > w ≥ 0.68. The fitnesses are calculated for an nh = 2 using equation (S1)
