Figure 3.
Boxplots showing that male fertilization success in paired-male fertilization trials (n=84, 53 trials shown) is higher for the male sharing a greater number of MHC class II alleles (MxyII) with the female in Chinook salmon (MCMCglmm analysis; pMCMC=0.008). Male fertilization success (%) is the proportion of 48 genotyped offspring sired by each male in a paired-male trial. Paired males that did not differ in MxyII (31 trials) cannot be assigned to different boxplots and thus, are not shown but were included in the MCMCglmm analysis.
