Mean time from colony foundation to 15th offspring, according to treatment. Bars show the mean duration of the period between the emergence of the 1st and 15th offspring. Means and their standard errors were predicted from the GLM. This measure of colony growth is significantly slower for the diploid male treatment than either outbred or inbred colonies (P < 0.001, see text).
