Table A2. Gonadal development of workers

Gonadal development of the worker that had the most advanced development in each group under three experimental treatments. 1Q/6W: one queen and six workers; 0Q/6W: queenless with six workers (0Q/6W); and 0Q/1W: one worker only. Numbers in the table represent counts of groups. We have excluded 10, 10 and 4 groups from treatments 0Q/1W, 1Q/6W and 0Q/6W respectively, because either workers had initial gonadal development, the queen died, the group had only male workers, or the group had only female workers.
