Figure 2.

The percentage of queens producing 5 and 15 offspring according to treatment. Black bars represent the outbred treatment, grey bars the inbred treatment and white bars the diploid male treatment. No significant difference was found between these values (P = 0.835 for 5 offspring & P = 0.248 for 15 offspring). Sample size within each treatment ranged from 6 to 18 and error bars show 95% shortest unbiased confidence limits.
