Average values for the response in the BC experiment, for resident-resident and hybrid-resident crosses. Vertical bars are 95% confidence intervals; significant differences between resident-resident and hybrid-resident crosses: *: P-value < 0.05; **: P-value < 0.01 (colour code as below). Black horizontal bar, BC for residents; green circle, BC for HOS as immigrant; orange square, BC for CHI as immigrant; blue triangle, BC for TUR as immigrant. FP: fertilisation proportion; EHP: egg-hatching proportion; CV: clone viability; R: net growth rate of the viable F1 clones; MPC: proportion of male-producing clones; and FDE: number of females produced per incubated diapausing egg.
