Figure 2From: Evolution of sociality by natural selection on variances in reproductive fitness: evidence from a social beeNormal quantile (Q-Q) plots of total brood weight for 1, 2, 3 and 4-female colonies from late spring and early summer. Significant deviations from normality (estimated quantiles from an expected normal distribution (straight line) and from the observed values) were found for the distribution of brood weight in 1 and 2-female colonies, but not for larger colony sizes (Table 1).Back to article page
