Figure 3. No overall effect of S-allele dominance on the total number of zerofold degenerate mutations (S_0f) in the linked genomic regions within 25 kb.

Each dot represents the mean number of mutations observed among haplotypes linked to one S-allele in one population. The correlations evaluated by a generalised linear model (GLM) are represented by lines, with confidence intervals represented in grey. The dominance was considered a continuous variable. (A) A. halleri. Black dots correspond to the Nivelle population, grey dots to the Mortagne population. The red arrow points to the copy of Ah15, corresponding to the S-allele whose sheltered load was phenotypically characterised by Llaurens et al., 2009b,Llaurens et al., 2009b in Nivelle. (B) A. lyrata. Red dots correspond to the IND population, black dots to the PIN population, and blue dots to the TSS population.
