Figure 2From: Genotype-specific interactions and the trade-off between host and parasite fitnessGenetic correlations between host and parasite fitness. Genetic correlations between host seed production (total mass of seeds in milligrams) and parasite transmission (number of successful transmissions). Each symbol represents a unique combination of host line and parasite strain. Symbols are distinguished according to the host line involved in the combination: Gb (red dots), Fin (black dots), Pyr (green dots), Sue (yellow dots), Tch (pink dots), Tsu (blue dots). Solid line: significant regression across the seven strains and control in combination with the host line Gb (y = -0.28x + 97.58; Spearman'rho = 0.81, p-value = 0.015). Dashed lines: non significant regressions for the host lines Fin (y = -0.66x + 61.32; ρ = -0.26, p-value = 0.53), Pyr (y = 0.43x + 17.10; ρ = 0.55, p-value = 0.16), Sue (y = -0.03x + 62.97; ρ = -0.29, p-value = 0.49), Tch (y = -0.07x + 64.15; ρ = -0.24, p-value = 0.57), and Tsu (y = -0.06x + 57.04; ρ = 0.17, p-value = 0.69).Back to article page
