Figure 3.

Correlation between family-wise survival rate and overall parasite load (calculated as the sum of standardized log-transformed infection intensities ± SE). The regression was calculated on family means weighted by the inverse of the standard errors associated with each family (R2 = 0.674, F1,7 = 14.442, P = 0.007). Circles represent segregating families and squares non-segregating families.
