Fig 1. Relative Cofor expression comparing nurses (N) and forager (F) expression.

“cal” = callows performing nursing tasks vs. foragers; “nur” = age-unknown nurses vs. foragers; “week1” = 1 week-old nurses vs. foragers; “week5” = 5 week-old nurses vs. foragers; “TN” = Age-unknown workers engaged in the task nursing and challenged to precocious foraging behavior; “TF” = Age-unknown workers engaged in the task foraging and challenged to revert to nursing behavior; DOL = division of labor. ** = p<0.008, ns = p>0.05. The number of replicate colonies is given below each box; each replicate represents five pooled nurse and worker heads, respectively.
