From: Non-quantitative adjustment of offspring sex ratios in pollinating fig wasps
Offspring number or sex ratio as a function of foundress number.
(a) Total average numbers of egg deposited (measured as the number of galled flowers) vs foundress numbers and (b) the sex ratio vs foundress numbers in F. racemosa. Results indicate that total egg deposition will decrease after foundress numbers reach a threshold and the male offspring sex ratio will increase as a function of foundress number. The male offspring sex ratio does not asymptotically reach 50%, but increases to above the 50% level to 70% of which is the male offspring sex ratio in the first hour egg deposition. The sample size N ≥ 20 in each type of the experiments.
