Fig. 3

Number of grilse and non-grilse individuals with each genotype (EE, EL, LL) for a SNP tagging vgll3 and b SNP tagging six6. Circles are proportional to sample size. E represents the allele that increases the odds of early maturation (early allele) and L represents the allele that decreases the odds of early maturation (late allele). Black squares indicate the mean phenotype value for each genotype (grilse = 1 and non-grilse = 2)
